+" Code formatting settings for Vim.

+" To enable this for GCC files by default, you can either source this file
+" in your .vimrc via autocmd:
+"   :au BufNewFile,BufReadPost path/to/gcc/* :so path/to/gcc/contrib/vimrc
+" or source the script manually for each newly opened file:
+"   :so contrib/vimrc
+" You could also use numerous plugins that enable local vimrc e.g.
+" mbr's localvimrc or thinca's vim-localrc (but note that the latter
+" is much less secure). To install local vimrc config, run
+"   $ make vimrc
+" from GCC build folder.
