It's a LaTeX style and a bunch of vector images, so that you can include ragefaces in your documents! It includes both .eps and .pdf sources, so this package should work with both latex and pdflatex, as long as you have the graphicx package.
For the lulz, I suppose.
Copy this folder into your LaTeX paths. If you have your own home folder texmf going, you should copy it into ~/texmf/tex/latex. Alternately, ln -s it. Or, if you can't be bothered to figure out how ~/texmf works (there are tutorials online), you can just copy the .sty file and the faces/ folder into the same folder as your project.
Then, check out example.tex to see how it's done.
convert.sh is a shell script I used to generate the eps and pdf files from svg sources (using inkscape). It also generates, more or less, the contents of f7u12.sty, less some changes. For more information, read the comments for convert.sh
The files in svg were supplied by redct's wonderful rageface svg pack. Credit where credit is due, and all that.
Make sure the faces collection is complete. There are definitely a few missing.
Make macro names consistent with those in /r/fffffffuuuuuuuuuuuu. Some of them are the same; Some are not.
Any differences between the conventions used in this package and the ones used in /r/fffffffuuuuuuuuuuuu should be documented.
Go for it! Fork on github, make changes, commit, make pull request. I'd recommend using the convert.sh script instead of doing a bunch of stuff by hand (when it makes sense, anyway).
Licensing for ragefaces is pretty sketch anyway. I think licensing the text parts of this package under the WTFPL is appropriate. ;) The images are under their own licenses, whatever those are.
