Currently, NetBeans project configuration, layout and management only supports a single project type. It would be nice
if the project orientation was changed completely so that it is just a project that has different 'facets' attached to
it. You could add the Java, C++ and Groovy facets.

This would be really helpful for me because I have a project that contains source code that has been ported from Java to
C++, C#, Python, Ruby and other languages. Rather than keep these in separate projects, I can use the same project and
run an entire build, test and release from a single location.

Having NetBeans support this model would really help. I realize that it could be a drastic shift, but considering the
increase usage of multiple languages in a single project (polyglot programming), this is something vital for IDEs.
IntelliJ is already and it seems like Eclipse is thinking along the same lines.
