+" Python imports insert completion
+" Maintainer: Sergey Matveev <stargrave@stargrave.org>
+" License: GNU General Public License version 3 of the License or later
+"
+" This plugin is intended for quick import-line insertion.
+" For example you have got "from foo.bar import Baz" import somewhere in
+" your Git-versioned code. In another file you can write "Baz" and then
+" press <F3> in insert mode. Completion menu will show you suggestions
+" of all import lines from your code containing Baz import.
+"
+" If you have Pylint or Pyflakes output in quickfix window, containing
+" unfedined variables errors, then you can you :call python#importcompl#all()
+" function. It will go through the quickfix list and find all possible
+" imports, sort them and insert under current cursor position.
+"
+" It uses external "git grep" call and assumes that "canonical" Python
+" import format is used (single import per line).
+" You can use http://www.git.stargrave.org/?p=pyimportcan.git;a=blob;f=pyimportcan.pl
+" utility to convert existing imports to that format.
