modules need own compile settings!!!

hi,
why have the modules not its own compile settings like:
- exclude from compile
- use compiler
- generate jar-file(hopefully in the future)

also it will be very cool if the module source will be only compiled(and added to jar?) when something in the module or in the module-dependecy has changed! imho the user must always configure ant-execution-points module specific:
execute
- after compilation "of a special module"
- before compilation "of a special module"
