" File: pum_snippet.vim
" Author: Michael Sanders (msanders42 [at] gmail [dot] com)

" Description: Uses snipMate to jump through function or method objc
" parameters when autocompleting. Used in cocoacomplete.vim.
" This function is invoked whenever pum_snippet is to be used; the keys are
" only mapped when used as the trigger, and then immediately unmapped to avoid
" breaking abbreviations, as well as other things.
