Does exactly the same as the original TextMate TODO bundle, instead of analyzing the (self defined) LaTeX commands \todo{}, \todo*{}, \fixme{}, \fixme*{}.
These commands are defined in the file todo_fixme.sty.
Please refer to the INSTALL file for installation instructions. I know, following these steps it's a bit annoying, but I couldn't figure out an easier way. If you know how, please contact me!
