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.
