# Regina - A Normal Surface Theory Calculator
# Python Test Suite Runner
#
# Copyright (c) 2007-2025, Ben Burton
# For further details contact Ben Burton (bab@debian.org).
#
# Usage: testcallback
#
# Runs some simple tests to ensure that Regina's Python module is playing
# nicely with pure Python callbacks in embedded subinterpreters.
#
# This script MUST be run from the python/testsuite directory in the
# build tree. It runs everything directly out of the build tree.
# It does not require regina to be installed on the system (and indeed
# it ignores any installation that it might find).
