Help!

I'm a newbie to Java and haven't been able to find out how to
'compile' apo-j source into a new jar file.

There is a defect in the .flame file format created by apo-j-25. This
defect is ignored by apo-j when reloading the file, but if I use
flam3-render to create the final image, the flame file fails due to
the error.

The last line of the .flame file might have "</Flames". It should be
"</Flames>". I edited main.java to fix this error, but I don't know
how to recompile apo-j into a new jar file.

Does someone know what the command line is to recompile apo-j?

I am running Ubuntu 8.04 with OpenJDK-6-jdk installed.
