There is a way to add the changes from catalyst_2 to master using git;
it will take someone who knows the code to make it happen, but you can
use rebase like so:

First, make sure that your copy of the repo is up to date and that you
have a branch called catalyst_2 that tracks the catalyst_2 branch. Then
do the following in the repo:

git checkout master
git rebase catalyst_2

Basically, this command will rework the master branch so that it
contains the changes that are only there but not in the catalyst_2
branch. You will have to resolve conflicts, then use git add and git
rebase--continue until that process is complete,.

Once you are done, run "git pull --rebase" to pick up the newest changes
in master, then git push to push everything back to master.

A conflict will look something like:

<<< HEAD
code
from
master
here
==========
code
from
other
branch
here
>>> catalyst_2

and you have to decide which piece of that code, or if it is parts of
both pieces, to keep, and remove the rest of it including the
<<< === and >>> lines.

For more info about how rebase works look at man git-rebase. Also I
learned a lot from http://progit.org/book and http://www.gitready.com.

Who knows the code well enough to do this?

Thanks,
