" Vim plugin for editing compressed files.
" Maintainer: Bram Moolenaar <Bram@vim.org>
" Last Change: 2010 Mar 10

" Exit quickly when:
" - this plugin was already loaded
" - when 'compatible' is set
" - some autocommands are already taking care of compressed files

  " Remove all gzip autocommands

  " Enable editing of gzipped files.
  " The functions are defined in autoload/gzip.vim.
  " Set binary mode before reading the file.
  " Use "gzip -d", gunzip isn't always available.
