#  The $(R) is a magic variable not defined anywhere in this source.
#  It's purpose is to allow an admin to create an installation 'tar'
#  file *without* actually installing it.  e.g.:
#
#  $ R=/home/root/tmp make install
#  $ cd /home/root/tmp
#  $ tar -cf ~/freeradius-package.tar *
#
#  The 'tar' file can then be un-tar'd on any similar machine.  It's a
#  cheap way of creating packages, without using a package manager.
#  Many of the platform-specific packaging tools use the $(R) variable
#  when creating their packages.
#
#  For compatibility with typical GNU packages (e.g. as seen in libltdl),
#  we make sure DESTDIR is defined.
