" This is the grep command I've always wanted.
" This plugin opens the results of 'grep -r' in a bottom window
" and uses 'git grep' when in a git repo and regular grep otherwise.

" <C-x><C-x> runs grep for the word under the cursor
" :G <word> runs grep 
" :Gi <word> runs grep as case-insensitive
