I did a quick attempt to integrate it in the Makefile - not pretty.
So I dropped that idea.
It is mainly that we should not fill up scripts/ with small
undocumented scripts.
Could you add something like this in the top of the file:
# Find the sum of the size of all files specified and
# output the size as an escaped hex string.
#
# Sample:
# $ ls -l foo
# $ -rw-rw-r-- 1 xxx xxx 146 May 8 22:28 foo
# $ bin_size foo
# $ \\x92\\x00\\x00\\x00
# 146 equals 92 hex
