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. |
---|

---|
13 | # NOTE: The concept of the minimum executive size is buried in this script. |
