2.1. Explicit Rules

Most rules you will write are explicit rules that specify particular files as targets and prerequisites. A rule can have more than one target. This means that each target has the same set of prerequisites as the others. If the targets are out of date, the same set of actions will be performed to update each one. For instance:

vpath.o variable.o: make.h config.h getopt.h gettext.h dep.h
