"""
Validates a large collection of web-accessible VOTable files.
Generates a report as a directory tree of HTML files.
Parameters
----------
urls : list of strings, optional
If provided, is a list of HTTP urls to download VOTable files
from. If not provided, a built-in set of ~22,000 urls
compiled by HEASARC will be used.
destdir : path, optional
The directory to write the report to. By default, this is a
directory called ``'results'`` in the current directory. If the
directory does not exist, it will be created.
multiprocess : bool, optional
If `True` (default), perform validations in parallel using all
of the cores on this machine.
stilts : path, optional
To perform validation with ``votlint`` from the the Java-based
`STILTS <http://www.star.bris.ac.uk/~mbt/stilts/>`_ VOTable
parser, in addition to `astropy.io.votable`, set this to the
path of the ``'stilts.jar'`` file. ``java`` on the system shell
path will be used to run it.
Notes
-----
Downloads of each given URL will be performed only once and cached
locally in *destdir*. To refresh the cache, remove *destdir*
first.
