-" 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 AllImportCompl()
-" 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.
