[bug#69074] [PATCH] gnu: Add python-pysmt.

[Troy Figiel <troy@troyfigiel.com>]

Hi Sören, here an example for python-pysmt, taken from your commit. It might
be good to add a comment why you cannot stick to a fixed version like
0.9.5. Or ask upstream for a new version :-)

* gnu/packages/python-xyz.scm (python-pysmt): New variable.
