"pydoc.vim: pydoc integration for vim
"performs searches and can display the documentation of python modules

"This plugin integrates the pydoc into vim. You can view the
"documentation of a module by using :Pydoc foo.bar.baz or search
"a word (uses pydoc -k) in the documentation by typing PydocSearch
"foobar. You can also view the documentation of the word under the
"cursor by pressing <leader>pw or the WORD (see :help WORD) by pressing
"<leader>pW. "This is very useful if you want to jump to a module which was found by
"PydocSearch. To have a browser like feeling you can use u and CTRL-R to
"go back and forward, just like editing normal text.
"If you want to use the script and pydoc is not in your PATH, just put a
"line like
" let g:pydoc_cmd = \"/usr/bin/pydoc" (without the backslash!!)
"in your .vimrc
