# This is a simple script to generate a C file that runs all the test cases
# present in .o files passed as arguments.
#
# Please, read the README file for more details.


# the trick here is getting all the test cases present in an object file using
# nm. All the tests must take and return void, start with "mutest_" and, of
# course, should not be static, which leads to a small limitation: all test
# cases must have unique names, even across test suites.

# the first argument should be mutest.h
