5#  This script gathers information related to the size of RTEMS
6#  using the GNU "size" command.
7#
8#  This script operates by summing up the sizes of the various
9#  object files which constitute a particular configuration of
10#  RTEMS.  This size information is gathered for placement in the
11#  brochure flyers and supplement manuals.
12#
13#  NOTE: The concept of the minimum executive size is buried in this script.
