" My ".vimrc" contains configures options which are core to Vim and are
" enumerated by the `:options` command. It groups the options into the
" same sections given by that command and in the same order for
" reference.
"
" Occasionally, each section contains other mappings or variable
" settings relevant to the options adjacent to them.
"
" The "$HOME/.vim" directory contains everything else, either as
" individual plugins (under "$HOME/.vim/[after/]{plugin,ftplugin}/") or
" as packages (under under "$HOME/.vim/pack/*/").
