<!-- 
template Ant build file for all projects that should go into the distribution. 
Fill out the properties at the beginning of the project definition.

The following things have to be set from the outside:

property name="jar" value="jar-name-without-suffix" -> the name of the resulting jar file
property name="distDir" value="dist-directory" -> the output directory for the resulting jar
path id="classpath" -> the filesets defining the classpath needed to compile the project
zipfileset id="jarfiles" -> the jar files to be merged with the project's classes
