Summary: Problem compiling with java -jar xmlvm.jar

Initial Comment:
Hello,

I am new using XmlVM, I must say that is an interesting and flexible project
which I'm attracted to.

Anyway, I'm confuse about how to use it. I downloaded Java 6 update 14,
Eclipse JEE Galileo, Subeclipse, then connect to svn repository give by you
and download the whole repository, last version of Apache ant command.
Finally I "ant" the repository and get the dist directory as the
documentation says, but after this some interesting things happened. When I
run "java -jar xmlvm.jar" an error display "Error: Need at least one --in
argument"

Then in order to test the "in", "out" and "target" options. I create an
environment variable "%xmlvm%=java -jar xmlvm.jar" simulating an alias in
unix. Then I just made a class in Eclipse adding reference to the xmlvm JARs
build it and then launching the following (the class contain the same code
to iHelloWorld example):

%xmlvm% --in=holaMundo.class --out="C:/"

and got:

Please Could you tell me what is wrong with steps.

PS.: It is intented to build a plugin for Eclipse,isn't it? In that case I
would like to learn and collaborate with the project, if it is possible and
you allow it, which I  think that deserve a great help as many people could
take benefit from it.
