# Sometimes we have a file-target that we want Make to always try to
# re-generate (such as compiling a Go program; we would like to let
# `go install` decide whether it is up-to-date or not, rather than
# trying to teach Make how to do that).  We could mark it as .PHONY,
# but that tells Make that "this isn't a real file that I expect to
# ever exist", which has a several implications for Make, most of
# which we don't want.  Instead, we can have them *depend* on a .PHONY
# target (which we'll name "FORCE"), so that they are always
# considered out-of-date by Make, but without being .PHONY themselves.
