Is this request still outstanding?

I'm willing to help contribute.  I will just need some guidance on how to use the source control for the project to get the source and guidance on how to build the package(s).  I have experience on other platforms (mostly mainframes and mini-computers) with assembler and C, but I have a good general knowledge of computer architecture and compiling and linking.

Currently I only have a Raspberry Pi to use for testing.  From reading the differences between Raspbian and Debian, I see that Debian packages compile for ARMv7 while Raspbian comiples for ARMv6 for use with the Pi's BCM SoC.

In theory I could test my changes on my Pi and then upload to have someone test on ARMv7.
