The Refuse Heap!
This is a little Clojure pastebin project that shells out to pygmentize for syntax highlighting. As such, it supports generally whatever Pygments supports.
lein deps ./fetch-pyg.sh lein run
I use a nice little locked padlock icon next to private pastes on user pages when said user is signed in and viewing his own page. This icon is part of the RRZE icon set that is licensed under Creative Commons Attribution-ShareAlike 3.0 Unported, which means that all I have to do is attribute the work to the creators. As such, here is me attributing.
