   5 #
   6 # check: run tests on all ccan modules (use 'make check V=--verbose' for more)
   7 #        Includes building libccan.a.
   8 # libccan.a: A library with all the ccan modules in it.
   9 # tools: build useful tools in tools/ dir.
  10 #        Especially tools/ccanlint/ccanlint and tools/namespacize.
  11 # distclean: destroy everything back to pristine state
  12
