Naming convention

Debian packages names require to be lowercase, hyphens, numbers and plus are allowed. Our name set_difference is already not valid! We will name the package set-difference even if the program name will still be set_difference. Later on, the format of the final binary package filename will be:

	<packagename>_<version>-<revision>_<arch>.deb

Our package filename will be:

	set-difference_1.0-1_i386.deb
