Make is a tool that optimize the shell actions. I mean it do not execute
commands that are not nedded for example recompile a file that haven't
change. In the Makefile, you've got rules to do that.
eg.
	toto.o: toto.c
		gcc -o toto.o toto.c

toto.o will be created only if the actual toto.o do not correspond to
toto.c. To know that Make check the creation dates of toto.c and toto.o!
