Michał Słomkowski - Original code was ported from their project(nginxfmt.py), and also used their readme.md as a template. some methods were rewritten or changed a bit, but most of the code follows their design.

Notes:

I am keeping the same licenese format as the one that was given by the owner of the project the code was ported from: Apache 2.0.
