Use subtree to merge commits from a project subdir (i.e., 'docs/') to gh-pages branch.

Creatings Project Pages using git-subtree

Many projects maintain their documentation within a subfolder of their repository (for example docs/). That way, as new features are added or existing features are modified, the documentation can be updated in the same commit. The git-subtree command can be an effective tool to merge those changes from the documentation subdirectory of your project to the root of the gh-pages branch.

Setup

According to the author of git-subtree, the command is included with git 1.7.11 and higher. However, it's in the "contrib" subtree for now, so it's not installed by default. Search for "git-subtree" in your system's package manager and install the package if it exists. If not, or if you are using an older version of git, the easiest way is to install git-subtree from the author's repo.

$ git clone https://github.com/apenwarr/git-subtree.git

An attempt at backbone-relational with knockback. Not sure why this isn't working. What am I missing?

Class in which only one instance of each subclass can exist in a set. Not sure if there is a better way to do this, but it works. Although I don't like that overriding `__eg__` breaks other things.
class Foo(object):
def __hash__(self):
return hash('.'.join([self.__class__.__module__, self.__class__.__name__]))
def __eq__(a, b):
return a.__hash__() == b.__hash__()
class Bar(Foo):
