"
" 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 [email protected] if you need help.
