Makefile Structure

• "A makefile consists of dependency lines of text which define a target ... followed by a colon and optionally a set of files on which the target depends."

        target [target ...]: [component ...]

• "After each dependency line, a series of lines of tab-indented text may follow which define how to transform the components (usually source files) into the target (usually the 'output')."

        target [target ...]: [component ...]
        [<TAB>command 1]
           .
           .
           .
        [<TAB>command n]

• "If any of the components have been modified, the command below are run."
