tpope/bundler won't work without this plugin on a project that uses dvm when mvim is not launched from within the project's directory. Using the command :Rvm will source the right GEM_HOME so that :Bedit [gem] is able to look in the right place.
We are purposefully including an older version of snipMate (0.84) from mikefarmer's repo so that it works with the long list of snippets available from the scrooloose/snippets collection. The current mainline snipMate seems to be no longer compatible with those snippets, but the scrooloose collection is still the best one to use.
