# This test Makefile highlights a few quirks in the way that pattern rules are processed.

# GNU Make will refuse to build deps_exist_but_rules_fail, even if dep1 exists,
# because the rule for building dep1 doesn't have a wildcard in.
# BioMake should do the same thing.

# GNU Make will build pattern_deps_exist_but_rules_fail, as long as pattern.dep exists,
# because the rule for building pattern.dep has a wildcard, so it ignores it.
# BioMake, again, should do the same thing.

# In the following case, if a file X.txt exists but a file X.src doesn't,
# Biomake should still go ahead and run the X.test rule, even if -B is specified.
