" 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.
