This document describes the Programming Methodology Framework also known under the PMF methodology. The methodology is based on the manifesto written by Zed A. Shaw which
describes a natural approach to software engineering with a strong focus on the act of programming. The PMF methodology uses a soft naming to allow for a non-partisan reference
to official engineering or project documents describing one of the most used software engineering methodologies.

NOTE: Changes at the bottom of this file overrides some earlier settings.
Once the style has stabilized and has been adopted as an official RFC style,
this can be consolidated so that style settings occur only in one place, but
for now the contents of this file consists first of the initial CSS work as
provided to the RFC Formatter (xml2rfc) work, followed by itemized and
commented changes found necssary during the development of the v3
formatters.
