-# 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
-
-# Trying to build the whole repo is usually a lose; there will be some
-# dependencies you don't have.
