Just a quick note that I have made few changes based on the feedback I have received. First you can install 'gist' using 'pip install python-gist', which should make it easier to install and alleviate some of the confusion with the existing package on pypi. Also, I have added fuzzy search to the tab-completion to make it easier to select gists.
This is the best gist management tool I've ever seen, and AFAIK the only one with a `gist edit` that lets you quickly edit your gists directly from your command line.
