#  size_rtems
#
#  This script gathers information related to the size of RTEMS
#  using the GNU "size" command.
#
#  This script operates by summing up the sizes of the various
#  object files which constitute a particular configuration of
#  RTEMS.  This size information is gathered for placement in the
#  brochure flyers and supplement manuals.
#
#  NOTE: The concept of the minimum executive size is buried in this script.
