This is only true for "normal" dependencies. If you specify a dependency
with two colons instead of one, then you can have a different action for
each dependency line:
# If bar1 is newer than foo, do this
foo:: bar1
echo bar1
# If bar2 is newer than foo, do this
foo:: bar2
echo bar2
I've never had a need for this feature, but it seems like it should be
useful for _something_. :-)
