Dave's .vimrc

.vimrc

" Dave Jacoby - 2011-02-13
"
" A key to .vimrc happiness is to have an alias like
"       alias vimrc="vi ~/.vimrc"
" in your .alias file or .bashrc or whatever, so, should you have
" a tweak to add or disable, you just go in and tweak it. Just
" a little pessimization removal
"
" Also, it is good to have the long version of settings in your
" configuration, so you have the best chance of reading and 
" understanding what it does. "se nu" is less understandable than
" "set numbers"

" double-quotes are comments
