"""
Performs 'make .htmls' in each directory to create html files from 
source files using $CLAW/doc/clawcode2html.py.

This is useful so that links will work, e.g. if you build the Sphinx
documentation locally.

Use make_clean.py to first remove old versions if desired, or
set remove_first to True below.
