guff is a ruby gem containing classes that let you produce nicely formatted Java code. Its intended to be used by code generation scripts that eliminate a lot of the ‘guff’ that often ends up being written on Java projects. One example of this is the java_testing_guff project, which generates java classes that provide fluent interfaces to configure mock objects.

I am the only developer right now.

Its beta quality, used in a couple of commercial projects.

Its not used by any external parties to my knowledge, but has been downloaded a few times from rubyforge :-)
