# testmaker.sh - assemble tests from backend-independent rulesets and
# backend-dependent boilerplate.  Generates both a Flex source file
# and an input text for it.
#
# The single argument is a testfile name to be generated.
# With the -d option, dump to stdourather than crating the file.
#
# To add a new back end named "foo", append "|foo" to the
# third case arm marked "# Add new back ends on this line".
