+" File: pylint_fn.vim
+" Author: Roman 'gryf' Dobosz (gryf73 at gmail.com)
+" Version: 1.1
+" Last Modified: 2015-09-20
+"
+" Description: " {{{
+"
+" Overview
+" --------
+" This plugin provides ":Pylint" command, which put pylint result into quickfix
+" buffer. This function does not uses pylint[1] command line utility, only
+" python pylint.lint module is used instead. So it makes the pylint
+" egg/package required for running this script.
+"
+" This script uses python, therefore VIm should be compiled with python
+" support. You can check it by issuing ":version" command, and search for
+" "+python" inside features list.
+"
+" Couple of ideas was taken from pyflakes.vim[2] plugin.
+"
+" Installation
+" ------------
+" 1. Copy the pylint_fn.vim file to the $HOME/.vim/ftplugin/python or
+"    $HOME/vimfiles/ftplugin/python or $VIM/vimfiles/ftplugin/python
+"    directory. If python directory doesn't exists, it should be created.
+"    Refer to the following Vim help topics for more information about Vim
+"    plugins:
+"       :help add-plugin
+"       :help add-global-plugin
+"       :help runtimepath
+" 2. It should be possible to import pylint from python interpreter (it should
+"    report no error):
+"    >>> import pylint
+"    >>>
+"    If there are errors, install pylint first. Simplest way to do it, is to
+"    use easy_install[3] shell command as a root:
+"    # easy_install pylint
+" 3. Restart Vim.
+" 4. You can now use the ":Pylint" which will examine current python buffer
+"    and open quickfix buffer with errors if any.
