" dpaste.vim: Vim plugin for pasting to dpaste.com (#django's favourite paste
" bin! )
" Maintainer:   Bartek Ciszkowski <bart.ciszk@gmail.com>
" Version:      0.1
"
" Thanks To: 
"   - Paul Bissex (pbx on irc) for creating dpaste :)
"   - The creator of the LodgeIt.vim plugin, in which I blatantly steal some
"   vim specific code from.
"
" Usage:
"   :Dpaste     create a paste from the current buffer or selection.
"   
" You can also map paste to CTRL + P, just add this to your .vimrc:
" map ^P :Dpaste<CR>
" (Where ^P is entered using CTRL + V, CTRL + P in Vim)
