+# make_version.py - generate version information

+# Author: Clancy Rowley
+# Date: 2 Apr 2015
+# Modified: Richard M. Murray, 28 Dec 2017
+#
+# This script is used to create the version information for the python-
+# control package.  The version information is now generated directly from
+# tags in the git repository.  Now, *before* running setup.py, one runs
+#
+#   python make_version.py
+#
+# and this generates a file with the version information.  This is copied
+# from binstar (https://github.com/Binstar/binstar) and seems to work well.
+#
+# The original version of this script also created version information for
+# conda, but this stopped working when conda v3 was released.  Instead, we
+# now use jinja templates in conda-recipe to create the conda information.
+# The current version information is used in setup.py, control/__init__.py,
+# and doc/conf.py (for sphinx).
