Hi,

I'm actually working on adding the following things to Jam at the moment:

- Parsing .class files to extract dependencies and put them into the dependency graph. - Modifying the Jambase to invoke the compiler once for the objects associated with a particular target (jar, whatever). This is necessary for correct builds as well as performance because dependencies from .class files only gives the set of files to be build, not the order. I know the compiler can do some of this, but I don't always trust it and I don't want to depend on having source files in directories following package name conventions. - Adding support for multiple compilers (Javac, jikes, gcj). - Adding support for native code generation using gcj from the same Jamfile as a conventional Java build.

Acunia-Jam has some interesting stuff (particularly the :P modifier). Acunia-JamJar (or something just like it) will be necessary.

I want to get my first version running in the next week or so, but that's what I said at the beginning of last week and other stuff intervened. I'll post here when it is ready.

Regards,
