I never remember how to do footnotes right using ReStructured Text.
If that, or something similar, happens to you, get my rst cheatsheet and print it, it's a two-sided A4 page.
This is an early version, the left-hand columns need lots of love.
Also, you may want to take a look at this one-page python cheatsheet, too.
Both are created using restructured text and rst2pdf, and licensed under Creative Commons.
I would love to see translations to other languages. If you want to help, contact me!
