Installing GEF -------------- First, you have to unzip the gef archive to a directory of your choice. It is recommended, that the last part of the resulting path is a subdirectory called "src". If you use another name for the subdirectory the build process might fail. The distribution is built using the Ant build system (http://jakarta.apache.org/ant). You will need to have Ant 1.2+. Once you have Ant installed, you can build the distribution simply by executing the command: ant compile This will compile all needed source files and copy the necessary helper files to the build directory. If you plan to use GEF as part of other projects, you might to build a jar file. Therefore you need to create a directory called "lib" on the same level your "src"-directory is on. Then simply type ant package This will do all the things "ant compile" does and additionally build a jar file called "gef.jar" in your "lib"-directory. Ant operates similarly to make, but instead of a makefile, Ant uses an XML build file. The build.xml file for this distribution has the several targets. You can type ant to get a list of the currently available targets including a short description of them. Thorsten Sturm Thorsten.Sturm@gentleware.de
