# Document Production

# Some Docutils installations keep the ".py" suffix for the various
# frontend programs, and some do not.  It's even possible there are
# links from one to the other.  Since the project can be checked out
# on any platform, we have to check for this every time we run the
# 'make'.  This is irritating.
