2.1 What a Rule Looks Like
==========================
A simple makefile consists of "rules" with the following shape:
TARGET ... : PREREQUISITES ...
RECIPE
...
...
A "target" is usually the name of a file that is generated by a
program; examples of targets are executable or object files. A target
can also be the name of an action to carry out, such as `clean' (*note
Phony Targets::).
A "prerequisite" is a file that is used as input to create the
target. A target often depends on several files.
