Example:

seqq: seqq.c
	gcc -Wall -Werror -o seqq seqq.c

The UNIX command make

• looks for a file named Makefile in the current directory
• and executes the gcc command

  prompt$ make gcc -Wall -Werror -o seqq seqq.c

• or does nothing if the dependencies haven't changed since the last make

  prompt$ make make: `seqq' is up to date.
