+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                          675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+
+	Appendix: How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+Xpdf
+====
+
+version 4.00
+2017-aug-10
+
+The Xpdf software and documentation are
+copyright 1996-2017 Glyph & Cog, LLC.
+
+Email: xpdf@xpdfreader.com
+WWW: http://www.xpdfreader.com/
+
+The PDF data structures, operators, and specification are
+documented in ISO 32000-1:2008.
+
+
+What is Xpdf?
+-------------
+
+Xpdf is an open source viewer for Portable Document Format (PDF)
+files.  (These are also sometimes also called 'Acrobat' files, from
+the name of Adobe's PDF software.)  The Xpdf project also includes a
+PDF text extractor, PDF-to-PostScript converter, and various other
+utilities.
+
+The Xpdf viewer uses the Qt cross-platform GUI toolkit.  The other
+command line utilties do not require Qt.
+
+
+License & Distribution
+----------------------
+
+Xpdf is licensed under the GNU General Public License (GPL), version 2
+or 3.  This means that you can distribute derivatives of Xpdf under
+any of the following:
+  - GPL v2 only
+  - GPL v3 only
+  - GPL v2 or v3
+
+The Xpdf source package includes the text of both GPL versions:
+COPYING for GPL v2, COPYING3 for GPL v3.
+
+Please note that Xpdf is NOT licensed under "any later version" of the
+GPL, as I have no idea what those versions will look like.
+
+If you are redistributing unmodified copies of Xpdf (or any of the
+Xpdf tools) in binary form, you need to include all of the
+documentation: README, man pages (or help files), COPYING, and
+COPYING3.
+
+If you want to incorporate the Xpdf source code into another program
+(or create a modified version of Xpdf), and you are distributing that
+program, you have two options: release your program under the GPL (v2
+and/or v3), or purchase a commercial Xpdf source license.
+
+If you're interested in commercial licensing, please see the Glyph &
+Cog web site:
+
+    http://www.glyphandcog.com/
+
+
+Compatibility
+-------------
+
+Xpdf uses the Qt toolkit and runs on Linux, Windows, and OS X -- and
+probably other systems that have a Qt port.
+
+The non-GUI command line utilities (pdftops, pdftotext, pdftohtml,
+pdfinfo, pdffonts, pdfdetach, pdftoppm, pdftopng, and pdfimages) run
+on Linux, Windows, and OS X -- and should run on pretty much any
+system with a decent C++ compiler.
+
+If you compile Xpdf for a system not listed on the web page, please
+let me know.  If you're willing to make your binary available by ftp
+or on the web, I'll be happy to add a link from the Xpdf web page.  I
+have decided not to host any binaries I didn't compile myself (for
+disk space and support reasons).
+
+If you can't get Xpdf to compile on your system, send me email and
+I'll try to help.
+
+
+Getting Xpdf
+------------
+
+The latest version is available from:
+
+  http://www.xpdfreader.com/
+
+Source code and several precompiled executables are available.
+
+Announcements of new versions are posted to comp.text.pdf and emailed
+to a list of people.  If you'd like to receive email notification of
+new versions, just let me know.
+
+
+Running Xpdf
+------------
+
+To run xpdf, simply type:
+
+  xpdf file.pdf
+
+To generate a PostScript file, run pdftops:
+
+  pdftops file.pdf
+
+To generate a plain text file, run pdftotext:
+
+  pdftotext file.pdf
+
+There are several additional utilities (which are fully described in
+their man pages):
+
+  pdftohtml -- converts a PDF file to HTML
+  pdfinfo -- dumps a PDF file's Info dictionary (plus some other
+             useful information)
+  pdffonts -- lists the fonts used in a PDF file along with various
+              information for each font
+  pdfdetach -- lists or extracts embedded files (attachments) from a
+               PDF file
+  pdftoppm -- converts a PDF file to a series of PPM/PGM/PBM-format
+              bitmaps
+  pdftopng -- converts a PDF file to a series of PNG image files
+  pdfimages -- extracts the images from a PDF file
+
+Command line options and many other details are described in the man
+pages: xpdf(1), etc.
+
+All of these utilities read an optional configuration file: see the
+xpdfrc(5) man page.
+
+
+Compiling Xpdf
+--------------
+
+See the separate file, INSTALL.
+
+
+Bugs
+----
+
+If you find a bug in Xpdf, i.e., if it prints an error message,
+crashes, or incorrectly displays a document, and you don't see that
+bug listed here, please send me email, with a pointer (URL, ftp site,
+etc.) to the PDF file.

+.RI [ PDF-file ]
+.SH DESCRIPTION
+.B Pdfdetach
+lists or extracts embedded files (attachments) from a Portable
+Document Format (PDF) file.
+.SH CONFIGURATION FILE
+Pdfdetach reads a configuration file at startup.  It first tries to
+find the user's private config file, ~/.xpdfrc.  If that doesn't
+exist, it looks for a system-wide config file, typically
+/usr/local/etc/xpdfrc (but this location can be changed when pdfinfo
+is built).  See the
+.BR xpdfrc (5)
+man page for details.
+.SH OPTIONS
+Some of the following options can be set with configuration file
+commands.  These are listed in square brackets with the description of
+the corresponding command line option.

+.B \-list
+List all of the embedded files in the PDF file.  File names are
+converted to the text encoding specified by the "\-enc" switch.
+.TP
+.BI \-save " number"
+Save the specified embedded file.  By default, this uses the file name
+associated with the embedded file (as printed by the "\-list" switch);
+the file name can be changed with the "\-o" switch.
+.TP
+.BI \-saveall
+Save all of the embedded files.  This uses the file names associated
+with the embedded files (as printed by the "\-list" switch).  By
+default, the files are saved in the current directory; this can be
+changed with the "\-o" switch.
+.TP
+.BI \-o " path"
+Set the file name used when saving an embedded file with the "\-save"
+switch, or the directory used by "\-saveall".
+.TP
+.BI \-enc " encoding-name"
+Sets the encoding to use for text output (embedded file names).  The
+.I encoding\-name
+must be defined with the unicodeMap command (see
+.BR xpdfrc (5)).
+This defaults to "Latin1" (which is a built-in encoding).
+.RB "[config file: " textEncoding ]
+.TP
+.BI \-opw " password"

+.SH SYNOPSIS

+[options]
+.I PDF-file image-root
+.SH DESCRIPTION
+.B Pdfimages
+saves images from a Portable Document Format (PDF) file as Portable
+Pixmap (PPM), Portable Graymap (PGM), Portable Bitmap (PBM), or JPEG
+files.
+.PP
+Pdfimages reads the PDF file, scans one or more pages,
+.IR PDF-file ,
+and writes one PPM, PGM, PBM, or JPEG file for each image,
+.IR image-root - nnnn . xxx ,
+where
+.I nnnn
+is the image number and
+.I xxx
+is the image type (.ppm, .pgm, .pbm, .jpg).
+.PP
+NB: pdfimages extracts the raw image data from the PDF file, without
+performing any additional transforms.  Any rotation, clipping,
+color inversion, etc. done by the PDF content stream is ignored.
+.SH CONFIGURATION FILE
+Pdfimages reads a configuration file at startup.  It first tries to
+find the user's private config file, ~/.xpdfrc.  If that doesn't
+exist, it looks for a system-wide config file, typically
+/usr/local/etc/xpdfrc (but this location can be changed when pdfimages

+.BI \-f " number"
+Specifies the first page to scan.
+.TP
+.BI \-l " number"
+Specifies the last page to scan.
+.TP
+.B \-j
+Normally, all images are written as PBM (for monochrome images), PGM
+(for grayscale images), or PPM (for color images) files.  With this
+option, images in DCT format are saved as JPEG files.  All non-DCT
+images are saved in PBM/PGM/PPM format as usual.  (Inline images are
+always saved in PBM/PGM/PPM format.)
+.TP
+.B \-raw
+Write all images in PDF-native formats.  Most of the formats are not
+standard image formats, so this option is primarily useful as input to
+a tool that generates PDF files.  (Inline images are always saved in
+PBM/PGM/PPM format.)
+.TP
+.B \-list
+Write a one-line summary to stdout for each image.  The summary
+provides the image file name, the page number, the image width and
+height, the horizontal and vertical resolution (DPI) as drawn, the
+color space type, and the number of bits per component (BPC).
+.TP
+.BI \-opw " password"
+Specify the owner password for the PDF file.  Providing this will
+bypass all security restrictions.

+pdftohtml \- Portable Document Format (PDF) to HTML converter
+(version 4.00)
+.SH SYNOPSIS
+.B pdftohtml
+[options]
+.I PDF-file
+.I HTML-dir
+.SH DESCRIPTION
+.B Pdftohtml
+converts Portable Document Format (PDF) files to HTML.
+.PP
+Pdftohtml reads the PDF file,
+.IR PDF-file ,
+and places an HTML file for each page, along with auxiliary images
+in the directory,
+.IR HTML-dir .
+The HTML directory will be created; if it already exists, pdftohtml
+will report an error.
+.SH CONFIGURATION FILE
+Pdftohtml reads a configuration file at startup.  It first tries to
+find the user's private config file, ~/.xpdfrc.  If that doesn't
+exist, it looks for a system-wide config file, typically
+/usr/local/etc/xpdfrc (but this location can be changed when pdftohtml
+is built).  See the
+.BR xpdfrc (5)
+man page for details.
+.SH OPTIONS
+Many of the following options can be set with configuration file
+commands.  These are listed in square brackets with the description of
+the corresponding command line option.
+.TP
+.BI \-f " number"
+Specifies the first page to convert.
+.TP
+.BI \-l " number"
+Specifies the last page to convert.
+.TP
+.BI \-z " number"
+Specifies the initial zoom level.  The default is 1.0, which means
+72dpi, i.e., 1 point in the PDF file will be 1 pixel in the HTML.
+Using \'-z 1.5', for example, will make the initial view 50% larger.
+.TP
+.BI \-r " number"
+Specifies the resolution, in DPI, for background images.  This
+controls the pixel size of the background image files.  The initial
+zoom level is controlled by the \'-z' option.  Specifying a larger
+\'-r' value will allow the viewer to zoom in farther without upscaling
+artifacts in the background.
+.TP
+.B \-skipinvisible
+Don't draw invisible text.  By default, invisible text (commonly used
+in OCR'ed PDF files) is drawn as transparent (alpha=0) HTML text.
+This option tells pdftohtml to discard invisible text entirely.
+.TP
+.B \-allinvisible
+Treat all text as invisible.  By default, regular (non-invisible) text
+is not drawn in the background image, and is instead drawn with HTML
+on top of the image.  This option tells pdftohtml to include the
+regular text in the background image, and then draw it as transparent
+(alpha=0) HTML text.
+.TP
+.BI \-opw " password"
+Specify the owner password for the PDF file.  Providing this will
+bypass all security restrictions.
+.TP
+.BI \-upw " password"
+Specify the user password for the PDF file.
+.TP
+.B \-q
+Don't print any messages or errors.

+.SH BUGS
+Some PDF files contain fonts whose encodings have been mangled beyond
+recognition.  There is no way (short of OCR) to extract text from
+these files.

+.TP
+.B \-level1
+Generate Level 1 PostScript.  The resulting PostScript files will be
+significantly larger (if they contain images), but will print on Level
+1 printers.  This also converts all images to black and white.  No
+more than one of the PostScript level options (\-level1, \-level1sep,

+.B \-level2gray
+Generate grayscale Level 2 PostScript.  All colors, including images,
+are converted to grayscale.
+.RB "[config file: " psLevel ]
+.TP
+.B \-level2sep
+Generate Level 2 separable PostScript.  All colors are converted to
+CMYK.  The PostScript separation convention operators are used to
+handle custom (spot) colors.
+.RB "[config file: " psLevel ]
+.TP
+.B \-level3
+Generate Level 3 PostScript.  This enables all Level 2 features plus
+CID font embedding and masked image generation.

+same as for \-level2Sep.
+.RB "[config file: " psLevel ]
+.TP
+.B \-eps
+Generate an Encapsulated PostScript (EPS) file.  An EPS file contains
+a single image, so if you use this option with a multi-page PDF file,
+you must use \-f and \-l to specify a single page.  No more than one of
+the mode options (\-eps, \-form) may be given.

+.B \-form
+Generate a PostScript form which can be imported by software that

+Generate OPI comments for all images and forms which have OPI
+information.  (This option is only available if pdftops was compiled
+with OPI support.)

+larger, but may be necessary for readable output.  Also, some
+PostScript interpreters do not have TrueType rasterizers.
+.RB "[config file: " psEmbedTrueTypeFonts ]

+PostScript fonts.
+.RB "[config file: " psEmbedCIDPostScriptFonts ]

+embedding.  No attempt is made to substitute for non-embedded CID
+TrueType fonts.
+.RB "[config file: " psEmbedCIDTrueTypeFonts ]
+.TP
+.B \-preload
+Convert PDF forms to PS procedures, and preload image data.  This uses
+more memory in the PostScript interpreter, but generates significantly
+smaller PS files in situations where, e.g., the same image is drawn on
+every page of a long document.
+.TP
+.BI \-paper " size"
+Set the paper size to one of "letter", "legal", "A4", or "A3".  This

+.B \-nocenter
+By default, PDF pages smaller than the paper (after any scaling) are

+.B \-userunit
+Honor the UserUnit settings on PDF pages when computing page/paper

+.BI \-l " number"
+Specifies the last page to convert.
+.TP
+.B \-layout
+Maintain (as best as possible) the original physical layout of the
+text.  The default is to \'undo' physical layout (columns,
+hyphenation, etc.) and output the text in reading order.  If the
+.B \-fixed
+option is given, character spacing within each line will be determined
+by the specified character pitch.
+.TP
+.B \-simple
+Similar to
+.BR \-layout ,
+but optimized for simple one-column pages.  This mode will do a better
+job of maintaining horizontal spacing, but it will only work properly
+with a single column of text.
+.TP
+.B \-table
+Table mode is similar to physical layout mode, but optimized for
+tabular data, with the goal of keeping rows and columns aligned (at
+the expense of inserting extra whitespace).  If the
+.B \-fixed
+option is given, character spacing within each line will be determined
+by the specified character pitch.
+.TP
+.B \-lineprinter
+Line printer mode uses a strict fixed-character-pitch and -height
+layout.  That is, the page is broken into a grid, and characters are
+placed into that grid.  If the grid spacing is too small for the
+actual characters, the result is extra whitespace.  If the grid
+spacing is too large, the result is missing whitespace.  The grid
+spacing can be specified using the
+.B \-fixed
+and
+.B \-linespacing
+options.
+If one or both are not given on the command line, pdftotext will
+attempt to compute appropriate value(s).
+.TP
+.B \-raw
+Keep the text in content stream order.  Depending on how the PDF file
+was generated, this may or may not be useful.
+.TP
+.BI \-fixed " number"
+Specify the character pitch (character width), in points, for physical
+layout, table, or line printer mode.  This is ignored in all other
+modes.
+.TP
+.BI \-linespacing " number"
+Specify the line spacing, in points, for line printer mode.  This is
+ignored in all other modes.
+.TP
+.B \-clip
+Text which is hidden because of clipping is removed before doing
+layout, and then added back in.  This can be helpful for tables where
+clipped (invisible) text would overlap the next column.
+.TP
+.B \-nodiag
+Diagonal text, i.e., text that is not close to one of the 0, 90, 180,
+or 270 degree axes, is discarded.  This is useful to skip watermarks
+drawn on top of body text, etc.
+.TP
+.BI \-enc " encoding-name"
+Sets the encoding to use for text output.  The
+.I encoding\-name
+must be defined with the unicodeMap command (see
+.BR xpdfrc (5)).
+The encoding name is case-sensitive.  This defaults to "Latin1" (which
+is a built-in encoding).
+.RB "[config file: " textEncoding ]
+.TP
+.BI \-eol " unix | dos | mac"
+Sets the end-of-line convention to use for text output.

+.SH NAME
+xpdfrc \- configuration file for Xpdf tools (version 4.00)
+.SH DESCRIPTION
+All of the Xpdf tools read a single configuration file.  If you have a
+.I .xpdfrc
+file in your home directory, it will be read.  Otherwise, a
+system-wide configuration file will be read from
+.IR /usr/local/etc/xpdfrc ,
+if it exists.  (This is its default location; depending on build
+options, it may be placed elsewhere.)  On Win32 systems, the
+.I xpdfrc
+file should be placed in the same directory as the executables.
+.PP
+The xpdfrc file consists of a series of configuration options, one
+per line.  Blank lines and lines starting with a \'#' (comments) are
+ignored.
+.PP
+Arguments may be quoted, using "double-quote" characters, e.g., for
+file names that contain spaces.
+.PP
+The following sections list all of the configuration options, sorted
+into functional groups.  There is an examples section at the end.
+.SH INCLUDE FILES
+.TP
+.BI include " config\-file"
+Includes the specified config file.  The effect of this is equivalent
+to inserting the contents of
+.I config\-file
+directly into the parent config file in place of the
+.I include
+command.  Config files can be nested arbitrarily deeply.
+.SH GENERAL FONT CONFIGURATION
+.TP
+.BI fontFile " PDF\-font\-name font\-file"
+Maps a PDF font,
+.IR PDF\-font\-name ,
+to a font for display or PostScript output.  The font file,
+.IR font\-file ,
+can be any type allowed in a PDF file.  This command can be used for
+8-bit or 16-bit (CID) fonts.
+.TP
+.BI fontDir " dir"
+Specifies a search directory for font files.  There can be multiple
+fontDir commands; all of the specified directories will be searched in
+order.  The font files can be Type 1 (.pfa or .pfb) or TrueType (.ttf
+or .ttc); other files in the directory will be ignored.  The font file
+name (not including the extension) must exactly match the PDF font
+name.  This search is performed if the font name doesn't match any of
+the fonts declared with the fontFile command.  There are no default
+fontDir directories.
+.TP
+.BI fontFileCC " registry\-ordering font\-file"
+Maps the
+.I registry\-ordering
+character collection to a font for display or PostScript output.  This
+mapping is used if the font name doesn't match any of the fonts
+declared with the fontFile, fontDir, psResidentFont16, or
+psResidentFontCC commands.
+.SH POSTSCRIPT FONT CONFIGURATION
+.TP
+.BR psFontPassthrough " yes | no"
+If set to "yes", pass 8-bit font names through to the PostScript
+output without substitution.  Fonts which are not embedded in the PDF
+file are expected to be available on the printer.  This defaults to
+"no".
+.TP
+.BI psResidentFont " PDF\-font\-name PS\-font\-name"
+When the 8-bit font
+.I PDF\-font\-name
+is used (without embedding) in a PDF file, it will be translated to
+the PostScript font
+.IR PS\-font\-name ,
+which is assumed to be resident in the printer.  Typically,
+.I PDF\-font\-name
+and
+.I PS\-font\-name
+are the same.  By default, only the Base-14 fonts are assumed to be
+resident.
+.TP
+.BI psResidentFont16 " PDF\-font\-name wMode PS\-font\-name encoding"
+When the 16-bit (CID) font
+.I PDF\-font\-name
+with writing mode
+.I wMode
+is used (without embedding) in a PDF file, it will be translated to
+the PostScript font
+.IR PS\-font\-name ,
+which is assumed to be resident in the printer.  The writing mode
+must be either \'H' for horizontal or \'V' for vertical.  The resident
+font is assumed to use the specified encoding (which must have been
+defined with the unicodeMap command).
+.TP
+.BI psResidentFontCC " registry\-ordering wMode PS\-font\-name encoding"
+When a 16-bit (CID) font using the
+.I registry\-ordering
+character collection and 
+.I wMode
+writing mode is used (without embedding) in a PDF file, the PostScript
+font,
+.IR PS\-font\-name ,
+is substituted for it.  The substituted font is assumed to be
+resident in the printer.  The writing mode must be either \'H' for
+horizontal or \'V' for vertical.  The resident font is assumed to use
+the specified encoding (which must have been defined with the
+unicodeMap command).
+.TP
+.BR psEmbedType1Fonts " yes | no"
+If set to "no", prevents embedding of Type 1 fonts in generated
+PostScript.  This defaults to "yes".
+.TP
+.BR psEmbedTrueTypeFonts " yes | no"
+If set to "no", prevents embedding of TrueType fonts in generated
+PostScript.  This defaults to "yes".
+.TP
+.BR psEmbedCIDTrueTypeFonts " yes | no"
+If set to "no", prevents embedding of CID TrueType fonts in generated
+PostScript.  For Level 3 PostScript, this generates a CID font, for
+lower levels it generates a non-CID composite font.  This defaults to
+"yes".
+.TP
+.BR psEmbedCIDPostScriptFonts " yes | no"
+If set to "no", prevents embedding of CID PostScript fonts in
+generated PostScript.  For Level 3 PostScript, this generates a CID
+font, for lower levels it generates a non-CID composite font.  This
+defaults to "yes".
+.SH POSTSCRIPT CONTROL
+.TP
+.BI psPaperSize " width(pts) height(pts)"
+Sets the paper size for PostScript output.  The
+.I width
+and
+.I height
+parameters give the paper size in PostScript points (1 point = 1/72
+inch).
+.TP
+.BR psPaperSize " letter | legal | A4 | A3 | match"
+Sets the paper size for PostScript output to a standard size.  The
+default paper size is set when xpdf and pdftops are built, typically
+to "letter" or "A4".  This can also be set to "match", which will set
+the paper size to match the size specified in the PDF file.
+.TP
+.BR psImageableArea " llx lly urx ury"
+Sets the imageable area for PostScript output.  The four integers are
+the coordinates of the lower-left and upper-right corners of the
+imageable region, specified in points (with the origin being the
+lower-left corner of the paper).  This defaults to the full paper
+size; the psPaperSize option will reset the imageable area
+coordinates.
+.TP
+.BR psCrop " yes | no"
+If set to "yes", PostScript output is cropped to the CropBox specified
+in the PDF file; otherwise no cropping is done.  This defaults to
+"yes".
+.TP
+.BR psUseCropBoxAsPage " yes | no"
+If set to "yes", PostScript output treats the CropBox as the page size.
+By default, this is "no", and the MediaBox is used as the page size.
+.TP
+.BR psExpandSmaller " yes | no"
+If set to "yes", PDF pages smaller than the PostScript imageable area
+are expanded to fill the imageable area.  Otherwise, no scaling is
+done on smaller pages.  This defaults to "no".
+.TP
+.BR psShrinkLarger " yes | no"
+If set to yes, PDF pages larger than the PostScript imageable area are
+shrunk to fit the imageable area.  Otherwise, no scaling is done on
+larger pages.  This defaults to "yes".
+.TP
+.BR psCenter " yes | no"
+If set to yes, PDF pages smaller than the PostScript imageable area
+(after any scaling) are centered in the imageable area.  Otherwise,
+they are aligned at the lower-left corner of the imageable area.  This
+defaults to "yes".
+.TP
+.BR psDuplex " yes | no"
+If set to "yes", the generated PostScript will set the "Duplex"
+pagedevice entry.  This tells duplex-capable printers to enable
+duplexing.  This defaults to "no".
+.TP
+.BR psLevel " level1 | level1sep | level2 | level2gray | level2sep | level3 | level3gray | level3Sep"
+Sets the PostScript level to generate.  This defaults to "level2".
+.TP
+.BR psPreload " yes | no"
+If set to "yes", PDF forms are converted to PS procedures, and image
+data is preloaded.  This uses more memory in the PostScript
+interpreter, but generates significantly smaller PS files in
+situations where, e.g., the same image is drawn on every page of a
+long document.  This defaults to "no".
+.TP
+.BR psOPI " yes | no"
+If set to "yes", generates PostScript OPI comments for all images and
+forms which have OPI information.  This option is only available if
+the Xpdf tools were compiled with OPI support.  This defaults to "no".
+.TP
+.BR psASCIIHex " yes | no"
+If set to "yes", the ASCIIHexEncode filter will be used instead of
+ASCII85Encode for binary data.  This defaults to "no".
+.TP
+.BR psLZW " yes | no"
+If set to "yes", the LZWEncode filter will be used for lossless
+compression in PostScript output; if set to "no", the RunLengthEncode
+filter will be used instead.  LZW generates better compression
+(smaller PS files), but may not be supported by some printers.  This
+defaults to "yes".
+.TP
+.BR psUncompressPreloadedImages " yes | no"
+If set to "yes", all preloaded images in PS files will uncompressed.
+If set to "no", the original compressed images will be used when
+possible.  The "yes" setting is useful to work around certain buggy
+PostScript interpreters.  This defaults to "no".
+.TP
+.BR psMinLineWidth " float"
+Set the minimum line width, in points, for PostScript output.  The
+default value is 0 (no minimum).
+.TP
+.BR psRasterResolution " float"
+Set the resolution (in dpi) for rasterized pages in PostScript output.
+(Pdftops will rasterize pages which use transparency.)  This defaults
+to 300.
+.TP
+.BR psRasterMono " yes | no"
+If set to "yes", rasterized pages in PS files will be monochrome
+(8-bit gray) instead of color.  This defaults to "no".
+.TP
+.BR psRasterSliceSize " pixels"
+When rasterizing pages, pdftops splits the page into horizontal
+"slices", to limit memory usage.  This option sets the maximum slice
+size, in pixels.  This defaults to 20000000 (20 million).
+.TP
+.BR psAlwaysRasterize " yes | no"
+If set to "yes", all PostScript output will be rasterized.  This
+defaults to "no".
+.TP
+.BR psNeverRasterize " yes | no"
+If set to "yes", PostScript output will never be rasterized.  This
+will likely result in incorrect output for PDF files that use
+transparency.  (If both psAlwaysRasterize and psNeverRasterize are set
+to "yes", the psAlwaysRasterize setting wins.)  This defaults to "no".
+.TP
+.BI psFile " file\-or\-command"
+Sets the default PostScript file or print command for xpdf.  Commands
+start with a \'|' character; anything else is a file.  If the file
+name or command contains spaces it must be quoted.  This defaults to
+unset, which tells xpdf to generate a name of the form <file>.ps for a
+PDF file <file>.pdf.
+.TP
+.BI fontDir " dir"
+See the description above, in the DISPLAY FONTS section.
+.SH TEXT CONTROL AND CHARACTER MAPPING
+.TP
+.BI textEncoding " encoding\-name"
+Sets the encoding to use for text output.  (This can be overridden
+with the "\-enc" switch on the command line.)  The
+.I encoding\-name
+must be defined with the unicodeMap command (see above).  This
+defaults to "Latin1".
+.TP
+.BR textEOL " unix | dos | mac"
+Sets the end-of-line convention to use for text output.  The options
+are:
+.nf
+
+    unix = LF
+    dos  = CR+LF
+    mac  = CR
+
+.fi
+(This can be overridden with the "\-eol" switch on the command line.)
+The default value is based on the OS where xpdf and pdftotext were
+built.
+.TP
+.BR textPageBreaks " yes | no"
+If set to "yes", text extraction will insert page breaks (form feed
+characters) between pages.  This defaults to "yes".
+.TP
+.BR textKeepTinyChars " yes | no"
+If set to "yes", text extraction will keep all characters.  If set to
+"no", text extraction will discard tiny (smaller than 3 point)
+characters after the first 50000 per page, avoiding extremely slow run
+times for PDF files that use special fonts to do shading or
+cross-hatching.  This defaults to "yes".
+.TP
+.BI nameToUnicode " map\-file"
+Specifies a file with the mapping from character names to Unicode.
+This is used to handle PDF fonts that have valid encodings but no
+ToUnicode entry.  Each line of a nameToUnicode file looks like this:
+
+.I "    " hex\-string name
+
+The
+.I hex\-string
+is the Unicode (UCS-2) character index, and
+.I name
+is the corresponding character name.  Multiple nameToUnicode files can
+be used; if a character name is given more than once, the code in the
+last specified file is used.  There is a built-in default
+nameToUnicode table with all of Adobe's standard character names.
+.TP
+.BI cidToUnicode " registry\-ordering map\-file"
+Specifies the file with the mapping from character collection to
+Unicode.  Each line of a cidToUnicode file represents one character:
+
+.I "    " hex\-string
+
+The
+.I hex\-string
+is the Unicode (UCS-2) index for that character.  The first line maps
+CID 0, the second line CID 1, etc.  File size is determined by size of
+the character collection.  Only one file is allowed per character
+collection; the last specified file is used.  There are no built-in
+cidToUnicode mappings.
+.TP
+.BI unicodeToUnicode " font\-name\-substring map\-file"
+This is used to work around PDF fonts which have incorrect Unicode
+information.  It specifies a file which maps from the given
+(incorrect) Unicode indexes to the correct ones.  The mapping will be
+used for any font whose name contains
+.IR font\-name\-substring .
+Each line of a unicodeToUnicode file represents one Unicode character:
+
+.RI "    " in\-hex " " out\-hex1 " " out\-hex2 " ..."
+
+The
+.I in\-hex
+field is an input (incorrect) Unicode index, and the rest of the
+fields are one or more output (correct) Unicode indexes.  Each
+occurrence of
+.I in\-hex
+will be converted to the specified output sequence.
+.TP
+.BI unicodeMap " encoding\-name map\-file"
+Specifies the file with mapping from Unicode to
+.IR encoding\-name .
+These encodings are used for text output (see below).  Each line of a
+unicodeMap file represents a range of one or more Unicode characters
+which maps linearly to a range in the output encoding:
+.nf
+
+.I "    " in\-start\-hex in\-end\-hex out\-start\-hex
+
+.fi
+Entries for single characters can be abbreviated to:
+.nf
+
+.I "    " in\-hex out\-hex
+
+.fi
+The
+.I in\-start\-hex
+and
+.I in\-end\-hex
+fields (or the single
+.I in\-hex
+field) specify the Unicode range.  The
+.I out\-start\-hex
+field (or the
+.I out\-hex
+field) specifies the start of the output encoding range.  The length
+of the
+.I out\-start\-hex
+(or
+.IR out\-hex )
+string determines the length of the output characters (e.g., UTF-8
+uses different numbers of bytes to represent characters in different
+ranges).  Entries must be given in increasing Unicode order.  Only one
+file is allowed per encoding; the last specified file is used.  The
+.IR Latin1 ,
+.IR ASCII7 ,
+.IR Symbol ,
+.IR ZapfDingbats ,
+.IR UTF-8 ,
+and
+.I UCS-2
+encodings are predefined.
+.TP
+.BI cMapDir " registry\-ordering dir"
+Specifies a search directory,
+.IR dir ,
+for CMaps for the
+.I registry\-ordering
+character collection.  There can be multiple directories for a
+particular collection.  There are no default CMap directories.
+.TP
+.BI toUnicodeDir " dir"
+Specifies a search directory,
+.IR dir ,
+for ToUnicode CMaps.  There can be multiple ToUnicode directories.
+There are no default ToUnicode directories.
+.TP
+.BI mapNumericCharNames " yes | no"
+If set to "yes", the Xpdf tools will attempt to map various numeric
+character names sometimes used in font subsets.  In some cases this
+leads to usable text, and in other cases it leads to gibberish --
+there is no way for Xpdf to tell.  This defaults to "yes".
+.TP
+.BI mapUnknownCharNames " yes | no"
+If set to "yes", and mapNumericCharNames is set to "no", the Xpdf
+tools will apply a simple pass-through mapping (Unicode index =
+character code) for all unrecognized glyph names.  (For CID fonts,
+setting mapNumericCharNames to "no" is unnecessary.)  In some cases,
+this leads to usable text, and in other cases it leads to gibberish --
+there is no way for Xpdf to tell.  This defaults to "no".
+.TP
+.BI mapExtTrueTypeFontsViaUnicode " yes | no"
+When rasterizing text using an external TrueType font, there are two
+options for handling character codes.  If
+mapExtTrueTypeFontsViaUnicode is set to "yes", Xpdf will use the font
+encoding/ToUnicode info to map character codes to Unicode, and then
+use the font's Unicode cmap to map Unicode to GIDs.  If
+mapExtTrueTypeFontsViaUnicode is set to "no", Xpdf will assume the
+character codes are GIDs (i.e., use an identity mapping).  This
+defaults to "yes".
+.SH RASTERIZER SETTINGS
+.TP
+.BR enableFreeType " yes | no"
+Enables or disables use of FreeType (a TrueType / Type 1 font
+rasterizer).  This is only relevant if the Xpdf tools were built with
+FreeType support.  ("enableFreeType" replaces the old
+"freetypeControl" option.)  This option defaults to "yes".
+.TP
+.BR disableFreeTypeHinting " yes | no"
+If this is set to "yes", FreeType hinting will be forced off.  This
+option defaults to "no".
+.TP
+.BR antialias " yes | no"
+Enables or disables font anti-aliasing in the PDF rasterizer.  This
+option affects all font rasterizers.  ("antialias" replaces the
+anti-aliasing control provided by the old "t1libControl" and
+"freetypeControl" options.)  This default to "yes".
+.TP
+.BR vectorAntialias " yes | no"
+Enables or disables anti-aliasing of vector graphics in the PDF
+rasterizer.  This defaults to "yes".
+.TP
+.BR antialiasPrinting " yes | no"
+If this is "yes", bitmaps sent to the printer will be antialiased
+(according to the "antialias" and "vectorAntialias" settings).  If
+this is "no", printed bitmaps will not be antialiased.  This defaults
+to "no".
+.TP
+.BR strokeAdjust " yes | no | cad"
+Sets the stroke adjustment mode.  If set to "no", no stroke adjustment
+will be done.  If set to "yes", normal stroke adjustment will be done:
+horizontal and vertical lines will be moved by up to half a pixel to
+make them look cleaner when vector anti-aliasing is enabled.  If set
+to "cad", a slightly different stroke adjustment algorithm will be
+used to ensure that lines of the same original width will always have
+the same adjusted width (at the expense of allowing gaps and overlaps
+between adjacent lines).  This defaults to "yes".
+.TP
+.BR screenType " dispersed | clustered | stochasticClustered"
+Sets the halftone screen type, which will be used when generating a
+monochrome (1-bit) bitmap.  The three options are dispersed-dot
+dithering, clustered-dot dithering (with a round dot and 45-degree
+screen angle), and stochastic clustered-dot dithering.  By default,
+"stochasticClustered" is used for resolutions of 300 dpi and higher,
+and "dispersed" is used for resolutions lower then 300 dpi.
+.TP
+.BI screenSize " integer"
+Sets the size of the (square) halftone screen threshold matrix.  By
+default, this is 4 for dispersed-dot dithering, 10 for clustered-dot
+dithering, and 100 for stochastic clustered-dot dithering.
+.TP
+.BI screenDotRadius " integer"
+Sets the halftone screen dot radius.  This is only used when
+screenType is set to stochasticClustered, and it defaults to 2.  In
+clustered-dot mode, the dot radius is half of the screen size.
+Dispersed-dot dithering doesn't have a dot radius.
+.TP
+.BI screenGamma " float"
+Sets the halftone screen gamma correction parameter.  Gamma values
+greater than 1 make the output brighter; gamma values less than 1 make
+it darker.  The default value is 1.
+.TP
+.BI screenBlackThreshold " float"
+When halftoning, all values below this threshold are forced to solid
+black.  This parameter is a floating point value between 0 (black) and
+1 (white).  The default value is 0.
+.TP
+.BI screenWhiteThreshold " float"
+When halftoning, all values above this threshold are forced to solid
+white.  This parameter is a floating point value between 0 (black) and
+1 (white).  The default value is 1.
+.TP
+.BI minLineWidth " float"
+Set the minimum line width, in device pixels.  This affects the
+rasterizer only, not the PostScript converter (except when it uses
+rasterization to handle transparency).  The default value is 0 (no
+minimum).
+.TP
+.BI enablePathSimplification " yes | no"
+If set to "yes", simplify paths by removing points where it won't make
+a significant difference to the shape.  The default value is "no".
+.TP
+.BI overprintPreview " yes | no"
+If set to "yes", generate overprint preview output, honoring the
+OP/op/OPM settings in the PDF file.  Ignored for non-CMYK output.  The
+default value is "no".
+.SH VIEWER SETTINGS
+These settings only apply to the Xpdf GUI PDF viewer.
+.TP
+.BR initialZoom " \fIpercentage\fR | page | width"
+Sets the initial zoom factor.  A number specifies a zoom percentage,
+where 100 means 72 dpi.  You may also specify \'page', to fit the page
+to the window size, or \'width', to fit the page width to the window
+width.
+.TP
+.BI defaultFitZoom " percentage"
+If xpdf is started with fit-page or fit-width zoom and no window
+geometry, it will calculate a desired window size based on the PDF
+page size and this defaultFitZoom value.  I.e., the window size will
+be chosen such that exactly one page will fit in the window at this
+zoom factor (which must be a percentage).  The default value is
+based on the screen resolution.
+.TP
+.BI initialSidebarState " yes | no"
+If set to "yes", xpdf opens with the sidebar (tabs, outline, etc.)
+visible.  If set to "no", xpdf opens with the sidebar collapsed.  The
+default is "no".
+.TP
+.BI paperColor " color"
+Set the "paper color", i.e., the background of the page display.  The
+color can be #RRGGBB (hexadecimal) or a named color.  This option will
+not work well with PDF files that do things like filling in white
+behind the text.
+.TP
+.BI matteColor " color"
+Set the matte color, i.e., the color used for background outside the
+actual page area.  The color can be #RRGGBB (hexadecimal) or a named
+color.
+.TP
+.BI fullScreenMatteColor " color"
+Set the matte color for full-screen mode.  The color can be #RRGGBB
+(hexadecimal) or a named color.
+.TP
+.BI popupMenuCmd " title command ..."
+Add a command to the popup menu.
+.I Title
+is the text to be displayed in the menu.
+.I Command
+is an Xpdf command (see the COMMANDS section of the
+.BR xpdf (1)
+man page for details).  Multiple commands are separated by whitespace.
+.TP
+.BI maxTileWidth " pixels"
+Set the maximum width of tiles to be used by xpdf when rasterizing
+pages.  This defaults to 1500.
+.TP
+.BI maxTileHeight " pixels"
+Set the maximum height of tiles to be used by xpdf when rasterizing
+pages.  This defaults to 1500.
+.TP
+.BI tileCacheSize " tiles"
+Set the maximum number of tiles to be cached by xpdf when rasterizing
+pages.  This defaults to 10.
+.TP
+.BI workerThreads " numThreads"
+Set the number of worker threads to be used by xpdf when rasterizing
+pages.  This defaults to 1.
+.TP
+.BI launchCommand " command"
+Sets the command executed when you click on a "launch"-type link.  The
+intent is for the command to be a program/script which determines the
+file type and runs the appropriate viewer.  The command line will
+consist of the file to be launched, followed by any parameters
+specified with the link.  Do not use "%s" in "command".  By default,
+this is unset, and Xpdf will simply try to execute the file (after
+prompting the user).
+.TP
+.BI movieCommand " command"
+Sets the command executed when you click on a movie annotation.  The
+string "%s" will be replaced with the movie file name.  This has no
+default value.
+.TP
+.BI bind " modifiers-key context command ..."
+Add a key or mouse button binding.
+.I Modifiers
+can be zero or more of:
+.nf
+
+    shift-
+    ctrl-
+    alt-
+
+.fi
+.I Key
+can be a regular ASCII character, or any one of:
+.nf
+
+    space
+    tab
+    return
+    enter
+    backspace
+    esc
+    insert
+    delete
+    home
+    end
+    pgup
+    pgdn
+    left / right / up / down        (arrow keys)
+    f1 .. f35                       (function keys)
+    mousePress1 .. mousePress7      (mouse buttons)
+    mouseRelease1 .. mouseRelease7  (mouse buttons)
+    mouseClick1 .. mouseClick7      (mouse buttons)
+
+.fi
+.I Context
+is either "any" or a comma-separated combination of:
+.nf
+
+    fullScreen / window       (full screen mode on/off)
+    continuous / singlePage   (continuous mode on/off)
+    overLink / offLink        (mouse over link or not)
+    scrLockOn / scrLockOff    (scroll lock on/off)
+
+.fi
+The context string can include only one of each pair in the above
+list.
+
+.I Command
+is an Xpdf command (see the COMMANDS section of the
+.BR xpdf (1)
+man page for details).  Multiple commands are separated by whitespace.
+
+The bind command replaces any existing binding, but only if it was
+defined for the exact same modifiers, key, and context.  All tokens
+(modifiers, key, context, commands) are case-sensitive.
+
+Example key bindings:
+.nf
+
+    # bind ctrl-a in any context to the nextPage
+    # command
+    bind ctrl-a any nextPage
+
+    # bind uppercase B, when in continuous mode
+    # with scroll lock on, to the reload command
+    # followed by the prevPage command
+    bind B continuous,scrLockOn reload prevPage
+
+.fi
+See the
+.BR xpdf (1)
+man page for more examples.
+.TP
+.BI unbind " modifiers-key context"
+Removes a key binding established with the bind command.  This is most
+useful to remove default key bindings before establishing new ones
+(e.g., if the default key binding is given for "any" context, and you
+want to create new key bindings for multiple contexts).
+.SH MISCELLANEOUS SETTINGS
+.TP
+.BI drawAnnotations " yes | no"
+If set to "no", annotations will not be drawn or printed.  The default
+value is "yes".
+.TP
+.BI drawFormFields " yes | no"
+If set to "no", form fields will not be drawn or printed.  The default
+value is "yes".
+.TP
+.BI enableXFA " yes | no"
+If set to "yes", an XFA form (if present) will be rendered in place of
+an AcroForm.  If "no", an XFA form will never be rendered.  This
+defaults to "yes".
+.TP
+.BI printCommands " yes | no"
+If set to "yes", drawing commands are printed as they're executed
+(useful for debugging).  This defaults to "no".
+.TP
+.BI errQuiet " yes | no"
+If set to "yes", this suppresses all error and warning messages from
+all of the Xpdf tools.  This defaults to "no".
