-"""
-A make-like way of executing the build, following the relationships between inputs/outputs
-
-This algorithm will lead to slower builds, will not be as flexible as "waf build", but
-it might be useful for building data files (?)
-
-It is likely to break in the following cases:
-- files are created dynamically (no inputs or outputs)
-- headers
-- building two files from different groups
