Make targets?

[Roman Kennke]

Hi,

I am looking for a make target, that only re-builds changed classes,
without the need to go through a complete 'make'. Would save me a lot of
time. Is this documented somewhere? My bash autocompletion gives me a
big list of make targets, I tried some but many seem to need some
environment variables set, that I haven't and thus fail. (for example
'make j2se-build' or 'make j2se-freshen' sounded promising).

Any ideas? make help only prints very few standard options.

Cheers, Roman
