Common INSTALL/DEINSTALL scripts and Makefile magic to automatically perform

many of the tasks that need to be done when package is installed or
deinstalled:

	* creating user/group for the package,

	* creating and removing directories with special permissions and
	  ownership,

	* copying config files to their final locations, and removing them
	  at deinstall time if they don't differ from the example ones,

	* reminding the package admin of files he may want to customize or
	  of files/directories he may want to remove.
