# Run all tests.
#
# Use -o to optimise the test programs before compiling them.
# Use -i to interpret the test programs instead of compiling them.
#
# You can just run this script with no arguments. If you want to run
# tests from a certain directory, specify that as the last argument.
# For example, if you are in the root directory, and want to run the
# tests in 'my_tests_dir` with optimisations enabled, you can run:
#
# $ ./bin/runtests.sh -o my_tests_dir
#
# Test programs (those ending with '.fo') are given their corresponding
# '.in' files as standard in when running, and are expected to produce
# the contents of the corresponding '.out' files, or the error of the
# corresponding '.err' files. If no corresponding '.in' file exists,
# the program is expected to fail at compile time.
#
# The Mars4_5.jar simulator must be in your Fasto "bin" directory, or
# you must export its location into the environment variable named MARS,
# unless you're using the '-i' option, in which case MARS is not used.
#
# If no argument is given, the script will run the tests in the current
# directory; otherwise it will use the first argument as a directory,
# and run the tests in that directory.
#
