" All system-wide defaults are set in $VIMRUNTIME/debian.vim and sourced by
" the call to :runtime you can find below.  If you wish to change any of those
" settings, you should do it in this file (/etc/vim/vimrc), since debian.vim
" will be overwritten everytime an upgrade of the vim packages is performed.
" It is recommended to make changes after sourcing debian.vim since it alters
" the value of the 'compatible' option.

" This line should not be removed as it ensures that various options are
" properly set to work with the Vim-related packages available in Debian.

" Vim will load $VIMRUNTIME/defaults.vim if the user does not have a vimrc.
" This happens after /etc/vim/vimrc(.local) are loaded, so it will override

" defaults.vim from being loaded.
" let g:skip_defaults_vim = 1

" NOTE: debian.vim sets 'nocompatible'.  Setting 'compatible' changes numerous
" options, so any other options should be set AFTER setting 'compatible'.
