Now that I read the asmifier description more carefully, I realized that 
it takes _classes_, not sources as input.

Had it been the latter, it would have been straightforward to modify it to
a compiler. But now that I found the answer to this question, it is clear
that the asm project doesn't help me much at this stage.

I already looked at the Eclipse compiler and it looked promising at the
first glance. All interfaces mentioned in the Compiler class seemed to
have a direct connection to the task of compiling. Now I only need to find
a good example/tutorial to get started.

Thanks to all, maybe I'll ask other questions (much) later when I start
doing custom bytecode transformations with ngrease.
