# make-test-arrays
#
# Given a test-arrays file, which specifies the test suite names, the
# names of the functions which perform those test suites, and
# descriptive comments, this script generates C structures for the
# mpi-test program.  The input consists of lines of the form:
#
# suite-name:function-name:comment
#
# The output is written to the standard output.  Blank lines are
# ignored, and comments beginning with '#' are stripped.
