391" Instructions for enabling "matchit" support:
392"
393" 1. Look for the latest "matchit" plugin at
394"
395"         http://www.vim.org/scripts/script.php?script_id=39
396"
397"    It is also packaged with Vim, in the $VIMRUNTIME/macros directory.
398"
399" 2. Copy "matchit.txt" into a "doc" directory (e.g. $HOME/.vim/doc).
400"
401" 3. Copy "matchit.vim" into a "plugin" directory (e.g. $HOME/.vim/plugin).
402"
403" 4. Ensure this file (ftplugin/ruby.vim) is installed.
404"
405" 5. Ensure you have this line in your $HOME/.vimrc:
406"         filetype plugin on
407"
408" 6. Restart Vim and create the matchit documentation:
409"
410"         :helptags ~/.vim/doc
411"
412"    Now you can do ":help matchit", and you should be able to use "%" on Ruby
413"    keywords.  Try ":echo b:match_words" to be sure.
414"
415" Thanks to Mark J. Reed for the instructions.  See ":help vimrc" for the
416" locations of plugin directories, etc., as there are several options, and it
417" differs on Windows.  Email [email protected] if you need help.
