 The 'prepare' target will download additional code (using CVS and http), so you need to be online to run it. The 'install' target can be run offline.
 
+Mac OS X: If you want to do Greenstone 2 style collection building, you need to have GDBM installed (http://www.gnu.org/software/gdbm/gdbm.html). Please set the gdbm.installed.path property (in build.properties) to the root of your gdbm installation if it is not installed in a default place. If you run GLI or GS2 collection building from the command line, you will need to set the DYLD_LIBRARY_PATH environment variable to include <path-to-gdbm>/lib.

 Configuring your installation:

 The file build.properties contains various parameters that can be set by the user. Please check these settings before running the install.
 
-Greenstone 3 uses the Tomcat servlet container. If you already have Tomcat running, you can set the 'tomcat.installed.path' property to the base directory of your Tomcat installation, and Greenstone will not download/install its own Tomcat. Please read the section "Using External Tomcat" for details about how to configure Tomcat for Greenstone.

-Greenstone 3 uses mysql for the collection database (with Greenstone 3 native building). If you already have mysql installed, set the 'mysql.installed.path' property to the base directory of your mysql installation, and Greenstone will not download/install mysql. Please read the section "Using external mysql server" for details about how to configure mysql for Greenstone.

-Greenstone 3 uses some parts of Greenstone 2 for collection building using the Librarian Interface. These will be installed during the Greenstone 3 installation process. If you have Greenstone 2 already installed and want to use that version instead, please set the gsdl2.installed.path property to be the root of your Greenstone 2 installation. Greenstone 3 will then use this installation rather than its own bits. (Note, be careful about compatibility between versions.) If you are using Greenstone 3 from CVS, and don't want to download the Greenstone 2 stuff, set the gsdl2.installed.path to any non-empty string.

 The compile target, under Linux, does Java and C/C++ compilation. For Windows, since Visual Studio is not a standard component, only Java compilation is carried out. Pre-compiled binaries are provided for the C/C++ components (packages and Greenstone 2 style building). If you have Visual Studio installed (version 6), you can run the compile-windows-c++ targets to compile the code locally. (Don't forget to setup the Visual Studio environment first, by running, e.g. C:/Program Files/Microsoft Visual Studio/VC98/Bin/VCVARS32.BAT or equivalent.)
