# Regina - A Normal Surface Theory Calculator
# Python Test Suite
#
# Copyright (c) 2007-2025, Ben Burton
# For further details contact Ben Burton (bab@debian.org).
#
# Usage: runbasic
#
# Runs the stripped-down basic Python interpreter, with all necessary paths
# set in the environment.
#
# In most cases nobody should need this script. It is provided mainly to help
# debug Python issues that arise when using an embedded interpreter.
#
# This script 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).
