" Vim global plugin that provides access to the codepad.org pastebin.
" Requires +python support.
"
" Add this to your ~/.vim/plugin/ directory. Then you can use
"
" :CPPaste
"     to send the current buffer to codepad.org and open your pasted code
"     in your webbrowser.
"
" :CPRun
"     to send the current buffer to codepad.org, execute it on their server,
"     and open both the pasted source and the program output in your browser.
"
" The correct filetype is automatically detected from the 'filetype' variable.
"
" Version:      1.3
" Last Change:  05 aug 2008
" Maintainer:   Nicolas Weber <nicolasweber at gmx.de>
