# Wrapper around morph for use by cmdtest tests. This does several things:
#
#   * simpler command lines for running morph, so that each test does not
#     need to add --no-default-config and other options every time
#   * replace temporary filenames ($DATADIR) in the output with a known
#     string ("TMP"), so that test output is deterministic

set -eu

# Set PATH to include the source directory. This is necessary for
# distributed builds, which invoke morph as a sub-process.
