# disable everything first and then reenable specific checks. For example, if
# you want to run only the similarities checker, you can use "--disable=all
# --enable=similarities". If you want to run only the classes checker, but have
# no Warning level messages displayed, use "--disable=all --enable=classes
# --disable=W".

Kapow! PoC
==========
This directory contains a somewhat working Kapow! implementation written
in Python.
The purpose of this implementation is to be an experimentation playfield
for the developers, allowing us to discuss and test new features
quickly.
Try the software within this directory with caution, anything can break
at any moment.
