# Makefile for errors test-suite
#
# This test-suite is for checking SWIG errors and warnings and uses
# Python as the target language.
#
# It compares the stderr output from SWIG to the contents of the .stderr
# file for each test case. The test cases are different to those used by
# the language module test-suites. The .i files in this directory are
# used instead of those in the parent directory.
#
# When adding a new test case, be sure to commit the expected output
# file (.stderr) in addition to the test case itself.
