# This script splits the data test files containing the test cases into
# individual files (one test case per file) suitable for use with afl
# (American Fuzzy Lop). http://lcamtuf.coredump.cx/afl/
#
# Usage: generate-afl-tests.sh <test data file path>
#  <test data file path> - should be the path to one of the test suite files
#                          such as 'test_suite_mpi.data'
