" Instructions for enabling "matchit" support:

" 1. Look for the latest "matchit" plugin at

" http://www.vim.org/scripts/script.php?script_id=39

" It is also packaged with Vim, in the $VIMRUNTIME/macros directory.

" 2. Copy "matchit.txt" into a "doc" directory (e.g. $HOME/.vim/doc).

" 3. Copy "matchit.vim" into a "plugin" directory (e.g. $HOME/.vim/plugin).

" 4. Ensure this file (ftplugin/ruby.vim) is installed.

" 5. Ensure you have this line in your $HOME/.vimrc:

" filetype plugin on

" 6. Restart Vim and create the matchit documentation:

" :helptags ~/.vim/doc

" Now you can do ":help matchit", and you should be able to use "%" on Ruby

" keywords. Try ":echo b:match_words" to be sure.

" Thanks to Mark J. Reed for the instructions. See ":help vimrc" for the

" locations of plugin directories, etc., as there are several options, and it

" differs on Windows. Email gsinclair@soyabean.com.au if you need help.
