list_xspec_models.py

#!/usr/bin/env python

"""

Usage:

  ./list_xspec_models.py outdir

Aim:

Create the AHELP/XSML tables needed by 'ahelp xs' to list the XSPEC
models. The output is to outdir/xs.xml and outdir must exist.

It is expected that the file is created by doc2ahelp.py but this is
provided for testing and special cases.
