This is much more exciting then your low key delivery Justin :)
So as a supported module we need to do the code review thing, check headers and
code coverage, and I need one page of docs ( as small as a single code example
you can inline in from a test case ).
So what can I do?
Vote +1
And check the headers once it is in.
Can you round up volunteers for doc page and test coverage?
