-The content of this directory is the automatic documentation for the Etadot calculation in Fortran created by FORD v5.0.6. We will get rid of the whole directory as soon as either FORD v6 properly recognises tabs, or source files have been sanitised wrt to tabs.
-
-fmw.md is the input for for FORD. Usage:

Documentation/FORD/V5/sanitise.sh

-#!/bin/bash

-# Sanitise the output of FORD so that it uses a local copy of the CC-BY img
-# rather than downloading it, and comment out the mathjax.js library being 
-# fetched (from mathjax.com) for data protection reasons.
