This plugin gives syntax highlighting to todo.txt files. It also defines a few mappings, to help with edition of these files:

<leader>-s : Sort the file

<leader>-d : Insert the current date

<leader>-D : Insert the current date with leading x (completed)

date<tab> : (Insert mode) Insert the current date

If you want the help installed run ":helptags ~/.vim/doc" inside vim after having copied the files. Then you will be able to get the commands help with: :h todo.txt
