Python hook skeleton for gitolite

Python hook skeleton for gitolite.

- Place this file as ~/.gitolite/hooks/common/<hook-name> (i.e. as
~/.gitolite/hooks/common/post-receive)
- Run "gl-setup" in console
- Define a number of function with @hook() decorators inside

Providing such configuration, every function is executed as a hook for a
repository which is provided either in @hook('argument') or in the function
name itself.

For example, following hook will be executed for the repository named 'repo'
(don't forget about the parentheses, please):

@hook()
def repo():
    ...


This is the hook for the repository 'another-repo'.

@hook('another-repo')
def another_repo_hook():
   ...

For more details about gitolite hooks see
http://sitaramc.github.com/gitolite/hooks.html

Hint: try to use it with OpenSSH wrapper (https://github.com/NetAngels/openssh-wrapper).
It can make it quite handy to execute commands on a remote host.
