# Wrapper script for calling the CAmkES code generator. You should use this as
# an entry point in preference to calling Python files directly because it
# checks the dependencies for you.

# If the user has the CAmkES accelerator enabled, first try to see if it can
# retrieve the requested output from the level A cache. Note that the
# accelerator returns non-zero on a cache miss and we just fall back on running
# the CAmkES code generator.
