Referring to http://docs.codehaus.org/display/IZPACK/Adding+a+set+of+files a <fileset> must have a "dir"-attribute and may have a "file"-attribut which is relativ to the "dir".
But the source code in CompilerConfig.java behaves different:
"file" is not relative to "dir"
"dir" is mandatory in line 3164, but it should be optional in lines 3165-3189)
If "dir" should be mandatory, "file" has to be relative to dir.
Either source or documentation should be adapted. Which variant should survive?
