ccan/Makefile

# Hacky makefile to compile everything and run the tests in some kind
# of sane order.

# Main targets:
# 
# check: run tests on all ccan modules (use 'make check V=--verbose' for more)
#        Includes building libccan.a.
# libccan.a: A library with all the ccan modules in it.
# tools: build useful tools in tools/ dir.
#        Especially tools/ccanlint/ccanlint and tools/namespacize.
# distclean: destroy everything back to pristine state

# Where make scores puts the results
