"[info] does nothing more than print its (expanded) argument(s) to standard output. No makefile name or line number is added. The result of the expansion of this function is the empty string."
Pymake doesn't print anything, though, instead calling log.info. I think it makes sense to have info behave the same as GNU make's info, i.e. as a generic print command.
