There's some documentation on our website:
 http://gcc.gnu.org/java/gcj2.html
 http://gcc.gnu.org/java/compile.html
What is missing from there is a simple example. Say you have 2 source
file and one class file: a.java, b.java and c.class. You build objects
first, by running `gcj -c' on every files:
 gcj -c a.java
 gcj -c b.java
 gcj -c c.class
Then you link all these objects into a single executable. --main let
you tell the compiler which class contains the main entry point. Let's
say class c in our example. You would link an executable like so:
 gcj a.o b.o c.o --main=c
This produces the default `a.out' executable. Of course, once you get
tired of repeating these steps, you write a makefile, or a least a
script which is fine if you project is small.

It is a native compiler. We strongly encourage you to download and
build gcc 3.0, a much better quality compiler.
