The sherpa.astro.utils.xspec module

Parser for XSPEC model files.

The XSPEC library [1] uses ASCII files to define models [2], and it can be useful to be able to read these files either to identify changes to the Sherpa code to support a new XSPEC release [3] or for writing a module for an XSPEC user model.
