"""
Code kwalitee checking tools for Invenio Python code.
Q: What is kwalitee?
A: <http://qa.perl.org/phalanx/kwalitee.html>
Usage: python kwalitee.py [options] <topsrcdir | file1.py file2.py ...>
General options::
-h, --help print this help
-V, --version print version number
-q, --quiet be quiet, print only warnings
Check options::
--stats generate kwalitee summary stats
--check-all perform all checks listed below
--check-some perform some (important) checks only
--check-errors check Python errors
--check-variables check Python variables
--check-indentation check Python code indentation
--check-whitespace check trailing whitespace
--check-docstrings check Python doctrings compliance
--check-pep8 check PEP8 compliance
Examples::
$ python kwalitee.py --stats ~/private/src/invenio/
$ python kwalitee.py --stats ../../websearch/lib/*.py
$ python kwalitee.py --check-some ../../websearch/lib/
$ python kwalitee.py --check-all ../../websearch/lib/search_engine.py
