Antigen seems to generate a unique temp dir where to
unjar the build.xml to process (with resources).
If the GUI is not used as an installer but as an ANT
app, this may produce lots of "antigen12399" and so on.
Better seems to be
1 antigen app = 1 temp dir (same name)
Best idea seems, take the project name
Is it possible to access it inside a jar, before
extract it ?
If yes, Project.getName()
If not, an antigen.property
(may also be used to override project.name ?)
