For developers: To help with configuring your environment to compile up the source code, Greenstone comes wiht a 'local' folder with some skeleton setup/devel files. These local versions will be called when the top level gs3-setup.sh/bat and gs3-devel.sh/bat are sourced (Unix) or run (Windows). If you wish to use your system java instead of a bundled java (in the binary release) or ext-cli version (for svn checkout of Greenstone), please set your JAVA_HOME in gs3-setup.sh/bat. For Windows, if you are compiling Greenstone, you will need to set the Visual Studio setup file path in local/gs3-devel.bat. Other Information: If you visit https://trac.greenstone.org/browser/local/greenstone3 you can see various OS specific local folders. These used to contain some necessary programs (such as ant, jdk, perl), but have been superseded by the ext-cli mechanism. However, what may still be useful are the READMEs for different OS variants, and looking at the settings used in the setup scripts.
