Comment 15 for bug 947358

Ok if you are ready to dive in check this first page out to get set

authenticate your code) and launchpad... which you have already and link
them and configure Bazaar.

This page shows you how to get the source code to fix, specifically from
debian... though you can read the whole page to get an understanding of
some other ways you could do it.

It seems kinda hard to figure out all the in an outs of everything at
first, but it is pretty straight forward. If you need any help, e-mail
me directly to keep clutter out of the bug report.
