- Make kaffe the main package, on which others can depend, and which has no
support for things like sound nor graphics. Bump its revision to 2.
While here, do some cleanup too.
- Add a kaffe-x11 package, that installs on top of kaffe, and which provides
the library needed for AWT support through X11.
- Add a kaffe-esound package, that installs on top of kaffe, and which provides
the library needed for sound support through esound (i.e., no more need for
the USE_ESOUND variable here).
- Remove the kaffe-nox11 package.
