Installed into usr/share/cruft/rules/package in the package build directory. This file is used to

debian/package.purge
Appended to usr/share/cruft/rules/package in the package build directory. This file is used to
register runtime files as belonging to this package. For claririty, directories should end with a
'/'.
Also, a snippet is appended to postrm with the needed rm-rf commands to remove these files on purge
phase.
Some basic templating is implemented: the #VERSION# tag will be replaced by the basic upstream
version.
