For Wget, we're now using OpenSSL. The openssl src code is on GS' SVN for compiling, while we're building the wget binary against OpenSSL's static libraries to produce GS binaries. However, OpenSSL is under a double license, ultimately incompatible with GPL, see https://www.gnu.org/licenses/license-list.en.html#OpenSSL. However, we can combine the GPL license of most of GS software with an exception for the OpenSSL part, which we've followed from https://opensource.stackexchange.com/questions/2233/gpl-v3-with-openssl-exception?rq=1

13 GNU GENERAL PUBLIC LICENSE
14 Version 2, June 1991
15
16 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
17 675 Mass Ave, Cambridge, MA 02139, USA
18 Everyone is permitted to copy and distribute verbatim copies
19 of this license document, but changing it is not allowed.
20
21 Preamble
22
23 The licenses for most software are designed to take away your
24freedom to share and change it. By contrast, the GNU General Public
25License is intended to guarantee your freedom to share and change free
26software--to make sure the software is free for all its users. This
27General Public License applies to most of the Free Software
28Foundation's software and to any other program whose authors commit to
29using it. (Some other Free Software Foundation software is covered by
30the GNU Library General Public License instead.) You can apply it to
31your programs, too.
32
33 When we speak of free software, we are referring to freedom, not
34price. Our General Public Licenses are designed to make sure that you
35have the freedom to distribute copies of free software (and charge for
36this service if you wish), that you receive source code or can get it
37if you want it, that you can change the software or use pieces of it
38in new free programs; and that you know you can do these things.
39
40 To protect your rights, we need to make restrictions that forbid
41anyone to deny you these rights or to ask you to surrender the rights.
42These restrictions translate to certain responsibilities for you if you
43distribute copies of the software, or if you modify it.
44
45 For example, if you distribute copies of such a program, whether
46gratis or for a fee, you must give the recipients all the rights that
47you have. You must make sure that they, too, receive or can get the
48source code. And you must show them these terms so they know their
49rights.
50
51 We protect your rights with two steps: (1) copyright the software, and
52(2) offer you this license which gives you legal permission to copy,
53distribute and/or modify the software.
54
55 Also, for each author's protection and ours, we want to make certain
56that everyone understands that there is no warranty for this free
57software. If the software is modified by someone else and passed on, we
58want its recipients to know that what they have is not the original, so
59that any problems introduced by others will not reflect on the original
60authors' reputations.
61
62 Finally, any free program is threatened constantly by software
63patents. We wish to avoid the danger that redistributors of a free
64program will individually obtain patent licenses, in effect making the
65program proprietary. To prevent this, we have made it clear that any
66patent must be licensed for everyone's free use or not licensed at all.
67
68 The precise terms and conditions for copying, distribution and
69modification follow.
70
71
72 GNU GENERAL PUBLIC LICENSE
73 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
74
75 0. This License applies to any program or other work which contains
76a notice placed by the copyright holder saying it may be distributed
77under the terms of this General Public License. The "Program", below,
78refers to any such program or work, and a "work based on the Program"
79means either the Program or any derivative work under copyright law:
80that is to say, a work containing the Program or a portion of it,
81either verbatim or with modifications and/or translated into another
82language. (Hereinafter, translation is included without limitation in
83the term "modification".) Each licensee is addressed as "you".
84
85Activities other than copying, distribution and modification are not
86covered by this License; they are outside its scope. The act of
87running the Program is not restricted, and the output from the Program
88is covered only if its contents constitute a work based on the
89Program (independent of having been made by running the Program).
90Whether that is true depends on what the Program does.
91
92 1. You may copy and distribute verbatim copies of the Program's
93source code as you receive it, in any medium, provided that you
94conspicuously and appropriately publish on each copy an appropriate
95copyright notice and disclaimer of warranty; keep intact all the
96notices that refer to this License and to the absence of any warranty;
97and give any other recipients of the Program a copy of this License
98along with the Program.
99
100You may charge a fee for the physical act of transferring a copy, and
101you may at your option offer warranty protection in exchange for a fee.
102
103 2. You may modify your copy or copies of the Program or any portion
104of it, thus forming a work based on the Program, and copy and
105distribute such modifications or work under the terms of Section 1
106above, provided that you also meet all of these conditions:
107
108 a) You must cause the modified files to carry prominent notices
109 stating that you changed the files and the date of any change.
110
111 b) You must cause any work that you distribute or publish, that in
112 whole or in part contains or is derived from the Program or any
113 part thereof, to be licensed as a whole at no charge to all third
114 parties under the terms of this License.
115
116 c) If the modified program normally reads commands interactively
117 when run, you must cause it, when started running for such
118 interactive use in the most ordinary way, to print or display an
119 announcement including an appropriate copyright notice and a
120 notice that there is no warranty (or else, saying that you provide
121 a warranty) and that users may redistribute the program under
122 these conditions, and telling the user how to view a copy of this
123 License. (Exception: if the Program itself is interactive but
124 does not normally print such an announcement, your work based on
125 the Program is not required to print an announcement.)
126
127
128These requirements apply to the modified work as a whole. If
129identifiable sections of that work are not derived from the Program,
130and can be reasonably considered independent and separate works in
131themselves, then this License, and its terms, do not apply to those
132sections when you distribute them as separate works. But when you
133distribute the same sections as part of a whole which is a work based
134on the Program, the distribution of the whole must be on the terms of
135this License, whose permissions for other licensees extend to the
136entire whole, and thus to each and every part regardless of who wrote it.
137
138Thus, it is not the intent of this section to claim rights or contest
139your rights to work written entirely by you; rather, the intent is to
140exercise the right to control the distribution of derivative or
141collective works based on the Program.
142
143In addition, mere aggregation of another work not based on the Program
144with the Program (or with a work based on the Program) on a volume of
145a storage or distribution medium does not bring the other work under
146the scope of this License.
147
148 3. You may copy and distribute the Program (or a work based on it,
149under Section 2) in object code or executable form under the terms of
150Sections 1 and 2 above provided that you also do one of the following:
151
152 a) Accompany it with the complete corresponding machine-readable
153 source code, which must be distributed under the terms of Sections
154 1 and 2 above on a medium customarily used for software interchange; or,
155
156 b) Accompany it with a written offer, valid for at least three
157 years, to give any third party, for a charge no more than your
158 cost of physically performing source distribution, a complete
159 machine-readable copy of the corresponding source code, to be
160 distributed under the terms of Sections 1 and 2 above on a medium
161 customarily used for software interchange; or,
162
163 c) Accompany it with the information you received as to the offer
164 to distribute corresponding source code. (This alternative is
165 allowed only for noncommercial distribution and only if you
166 received the program in object code or executable form with such
167 an offer, in accord with Subsection b above.)
168
169The source code for a work means the preferred form of the work for
170making modifications to it. For an executable work, complete source
171code means all the source code for all modules it contains, plus any
172associated interface definition files, plus the scripts used to
173control compilation and installation of the executable. However, as a
174special exception, the source code distributed need not include
175anything that is normally distributed (in either source or binary
176form) with the major components (compiler, kernel, and so on) of the
177operating system on which the executable runs, unless that component
178itself accompanies the executable.
179
180If distribution of executable or object code is made by offering
181access to copy from a designated place, then offering equivalent
182access to copy the source code from the same place counts as
183distribution of the source code, even though third parties are not
184compelled to copy the source along with the object code.
185
186
187 4. You may not copy, modify, sublicense, or distribute the Program
188except as expressly provided under this License. Any attempt
189otherwise to copy, modify, sublicense or distribute the Program is
190void, and will automatically terminate your rights under this License.
191However, parties who have received copies, or rights, from you under
192this License will not have their licenses terminated so long as such
193parties remain in full compliance.
194
195 5. You are not required to accept this License, since you have not
196signed it. However, nothing else grants you permission to modify or
197distribute the Program or its derivative works. These actions are
198prohibited by law if you do not accept this License. Therefore, by
199modifying or distributing the Program (or any work based on the
200Program), you indicate your acceptance of this License to do so, and
201all its terms and conditions for copying, distributing or modifying
202the Program or works based on it.
203
204 6. Each time you redistribute the Program (or any work based on the
205Program), the recipient automatically receives a license from the
206original licensor to copy, distribute or modify the Program subject to
207these terms and conditions. You may not impose any further
208restrictions on the recipients' exercise of the rights granted herein.
209You are not responsible for enforcing compliance by third parties to
210this License.
211
212 7. If, as a consequence of a court judgment or allegation of patent
213infringement or for any other reason (not limited to patent issues),
214conditions are imposed on you (whether by court order, agreement or
215otherwise) that contradict the conditions of this License, they do not
216excuse you from the conditions of this License. If you cannot
217distribute so as to satisfy simultaneously your obligations under this
218License and any other pertinent obligations, then as a consequence you
219may not distribute the Program at all. For example, if a patent
220license would not permit royalty-free redistribution of the Program by
221all those who receive copies directly or indirectly through you, then
222the only way you could satisfy both it and this License would be to
223refrain entirely from distribution of the Program.
224
225If any portion of this section is held invalid or unenforceable under
226any particular circumstance, the balance of the section is intended to
227apply and the section as a whole is intended to apply in other
228circumstances.
229
230It is not the purpose of this section to induce you to infringe any
231patents or other property right claims or to contest validity of any
232such claims; this section has the sole purpose of protecting the
233integrity of the free software distribution system, which is
234implemented by public license practices. Many people have made
235generous contributions to the wide range of software distributed
236through that system in reliance on consistent application of that
237system; it is up to the author/donor to decide if he or she is willing
238to distribute software through any other system and a licensee cannot
239impose that choice.
240
241This section is intended to make thoroughly clear what is believed to
242be a consequence of the rest of this License.
243
244
245 8. If the distribution and/or use of the Program is restricted in
246certain countries either by patents or by copyrighted interfaces, the
247original copyright holder who places the Program under this License
248may add an explicit geographical distribution limitation excluding
249those countries, so that distribution is permitted only in or among
250countries not thus excluded. In such case, this License incorporates
251the limitation as if written in the body of this License.
252
253 9. The Free Software Foundation may publish revised and/or new versions
254of the General Public License from time to time. Such new versions will
255be similar in spirit to the present version, but may differ in detail to
256address new problems or concerns.
257
258Each version is given a distinguishing version number. If the Program
259specifies a version number of this License which applies to it and "any
260later version", you have the option of following the terms and conditions
261either of that version or of any later version published by the Free
262Software Foundation. If the Program does not specify a version number of
263this License, you may choose any version ever published by the Free Software
264Foundation.
265
266 10. If you wish to incorporate parts of the Program into other free
267programs whose distribution conditions are different, write to the author
268to ask for permission. For software which is copyrighted by the Free
269Software Foundation, write to the Free Software Foundation; we sometimes
270make exceptions for this. Our decision will be guided by the two goals
271of preserving the free status of all derivatives of our free software and
272of promoting the sharing and reuse of software generally.
273
274 NO WARRANTY
275
276 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
277FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
278OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
279PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
280OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
281MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
282TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
283PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
284REPAIR OR CORRECTION.
285
286 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
287WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
288REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
289INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
290OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
291TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
292YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
293PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
294POSSIBILITY OF SUCH DAMAGES.
295
296 END OF TERMS AND CONDITIONS
297
298
299 How to Apply These Terms to Your New Programs
300
301 If you develop a new program, and you want it to be of the greatest
302possible use to the public, the best way to achieve this is to make it
303free software which everyone can redistribute and change under these terms.
304
305 To do so, attach the following notices to the program. It is safest
306to attach them to the start of each source file to most effectively
307convey the exclusion of warranty; and each file should have at least
308the "copyright" line and a pointer to where the full notice is found.
309
310 <one line to give the program's name and a brief idea of what it does.>
311 Copyright (C) 19yy <name of author>
312
313 This program is free software; you can redistribute it and/or modify
314 it under the terms of the GNU General Public License as published by
315 the Free Software Foundation; either version 2 of the License, or
316 (at your option) any later version.
317
318 This program is distributed in the hope that it will be useful,
319 but WITHOUT ANY WARRANTY; without even the implied warranty of
320 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
321 GNU General Public License for more details.
322
323 You should have received a copy of the GNU General Public License
324 along with this program; if not, write to the Free Software
325 Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
326
327Also add information on how to contact you by electronic and paper mail.
328
329If the program is interactive, make it output a short notice like this
330when it starts in an interactive mode:
331
332 Gnomovision version 69, Copyright (C) 19yy name of author
333 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
334 This is free software, and you are welcome to redistribute it
335 under certain conditions; type `show c' for details.
336
337The hypothetical commands `show w' and `show c' should show the appropriate
338parts of the General Public License. Of course, the commands you use may
339be called something other than `show w' and `show c'; they could even be
340mouse-clicks or menu items--whatever suits your program.
341
342You should also get your employer (if you work as a programmer) or your
343school, if any, to sign a "copyright disclaimer" for the program, if
344necessary. Here is a sample; alter the names:
345
346 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
347 `Gnomovision' (which makes passes at compilers) written by James Hacker.

351
352This General Public License does not permit incorporating your program into
353proprietary programs. If your program is a subroutine library, you may
354consider it more useful to permit linking proprietary applications with the
355library. If this is what you want to do, use the GNU Library General
356Public License instead of this License.
