" repeat.vim - Let the repeat command repeat plugin maps
" Maintainer:   Tim Pope
" Version:      1.0

" Installation:
" Place in either ~/.vim/plugin/repeat.vim (to load at start up) or
" ~/.vim/autoload/repeat.vim (to load automatically as needed).
"
" 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.
