+" The following commands only apply to files under CVS source control.
+"
+" CVSEdit Performs "cvs edit" on the current file.
+"
+" CVSEditors Performs "cvs editors" on the current file.
+"
+" CVSUnedit Performs "cvs unedit" on the current file.
+"
+" CVSWatch Takes an argument which must be one of [on|off|add|remove].
+" Performs "cvs watch" with the given argument on the current
+" file.
+"
+" CVSWatchers Performs "cvs watchers" on the current file.
+"
+" CVSWatchAdd Alias for "CVSWatch add"
+"
+" CVSWatchOn Alias for "CVSWatch on"
+"
+" CVSWatchOff Alias for "CVSWatch off"
+"
+" CVSWatchRemove Alias for "CVSWatch remove"
+"
+" Mapping documentation: {{{2
+"
+" By default, a mapping is defined for each command. User-provided mappings
+" can be used instead by mapping to <Plug>CommandName, for instance:
+"
+" nnoremap ,ce <Plug>CVSEdit

+" The default mappings are as follow:
+"
+" <Leader>ce CVSEdit

+" <Leader>ct CVSUnedit
+" <Leader>cwv CVSWatchers

+" 'cvs' executed from the user's executable path.
+"
+" VCSCommandCVSDiffOpt
+" This variable, if set, determines the options passed to the cvs diff
+" command. If not set, it defaults to 'u'.
