# I run a wiki on Gitit at http://wiki.wcaleb.rice.edu. It's usually | |
# updated by pushing to the wiki's remote git repo from my local machine. | |
# I have a `post-receive` hook in that repo that runs this script, like so: | |
# | |
# unset GIT_DIR | |
# python /path/to/wikitweet.py | |
# | |
# Now, whenever I push to the repo, the script looks to see which files have | |
# been changed and tweets about the update to https://twitter.com/wcaleb | |
