-- This is a program that converts docbook xml to optionally ANSI colored

-- See https://tdg.docbook.org/ for more information about the docbook format.

-- This conversion could also be achieved by using pandoc.
-- However because of the custom color formatting, we would probably
-- end up having to write custom conversion logic for every tag to be
-- consumed by pandoc anyway. So instead, I am just planning on keeping
-- my own module parsing raw xml tags (for now).
