+" repeat.vim - Let the repeat command repeat plugin maps
+" Maintainer:   Tim Pope
+" Version:      1.2
+" GetLatestVimScripts: 2136 1 :AutoInstall: repeat.vim
+
+" Installation:
+" Place in either ~/.vim/plugin/repeat.vim (to load at start up) or
+" ~/.vim/autoload/repeat.vim (to load automatically as needed).
+"
+" License:
+" Copyright (c) Tim Pope.  Distributed under the same terms as Vim itself.
+" See :help license
+"
+" Developers:
+" Basic usage is as follows:
+"
+"   silent! call repeat#set("\<Plug>MappingToRepeatCommand",3)
+"
+" The first argument is the mapping that will be invoked when the |.| key is
+" pressed.  Typically, it will be the same as the mapping the user invoked.
+" This sequence will be stuffed into the input queue literally.  Thus you must
+" encode special keys by prefixing them with a backslash inside double quotes.
+"
+" The second argument is the default count.  This is the number that will be
+" prefixed to the mapping if no explicit numeric argument was given.  The
+" value of the v:count variable is usually correct and it will be used if the
+" second parameter is omitted.  If your mapping doesn't accept a numeric
+" argument and you never want to receive one, pass a value of -1.
+"
+" Make sure to call the repeat#set function _after_ making changes to the
+" file.
+"
+" For mappings that use a register and want the same register used on
+" repetition, use:
+"
+"   silent! call repeat#setreg("\<Plug>MappingToRepeatCommand", v:register)
+"
+" This function can (and probably needs to be) called before making changes to
+" the file (as those typically clear v:register).  Therefore, the call sequence
+" in your mapping will look like this:
+"
+"   nnoremap <silent> <Plug>MyMap
+"   \   :<C-U>silent! call repeat#setreg("\<lt>Plug>MyMap", v:register)<Bar>
+"   \   call <SID>MyFunction(v:register, ...)<Bar>
+"   \   silent! call repeat#set("\<lt>Plug>MyMap")<CR>
