This project is available for forking on GitHub:
Embed GitHub Gists into

to embed by hand in the event that a Gist needs to be embedded somewhere in
the page that does not pass through the shortcode filters.
Examples:
[gist id=546764]
[gist id=546764 file=file.txt]
[gist id=546764 file=file.txt bump=1]
