#!/usr/bin/env python
# Convert Tim-style text to html or qml
#
# The Rules:
# - Lines with all upper case words to h2 or h3 capwords depending on next line underlining (first to h1/title though)
# (must be 3 chars or more)
# (todo: relax to not all upper case... no need to capwords if not)
# - Other text to p, blank lines break a p
# - Lines beginning with "- " (NB space) to ul/li (bulleted)
# - Lines beginning with "-?" (no space) to ul/li (?) with <br> at end of first line
# - Lines ending with ":" <br>
# - Words delim <xxx> to <i>xxx</i>
# "$ " at start of line indicates one line of code (add <br> too)
