Seconded. Really good for preprocessing of data files, or repetitive data pipelines. Just set up a naming convention for the intermediate files and define transformation rules. Then you can drop one new file in somewhere, type "make", and the minimal set of processing will just run. If you need more power, use the wildcard expansion and "patsubst" type rules to define rules at runtime.
