 Fantastic! Don't worry about merging. When doing development what you'll
 generally want to do is...

 # switch to your master branch and make sure it's up to date
 git checkout master
 git pull origin

 # make a new branch where you implement your feature
 git checkout -b my_spiffy_new_feature
 <do your work>

 # when you're done again make sure your master branch its up to date
 git fetch origin

 # this will update your feature branch to be off of stem's current master
 git rebase origin/master

 # pushes into your repository
 git push my_remote

 Note that these commands will vary based on what you're calling your
 remotes. If you're new to git then I'd suggest...

 Personally I found it to be very well written. There's no need to do a
 merge (though it doesn't hurt). I can then easily cherry-pick or merge
 your changes.

 All this said though we have a couple issue that needs to be addressed
 before I can look at your branch...

 +"""^M
 +Parsing for Tor server descriptors, which contains the infrequently
 changing^M
 +information about a Tor relay (contact information, exit policy, public
 keys,^M
 ...

 See the ^M at the end of the lines? Those are Windows newlines. Whatever
 editor you're using are introducing them. This causes a couple issues...
 - A simple diff claims that every line is changed. I can tell diff to
 ignore whitespace, but it's still annoying.
 - Mixed newlines can confuse a lot of tools. They're very bad to introduce
 into code.

 So we need to both strip these out and figure out a method for you to edit
 files without introducing them. This is a common gotcha so I'm sure google
 will have some good suggestions.

 For my part I should make the whitespace checker look for these. Also, we
 need to make non-builtin dependencies optional. Otherwise users will
 get...

 I'm not quite sure how we should handle this, logging a warning once if
 they try to verify without the module or something else...
