# 2.5: support functions

# Figure out how to extract size information from binaries. We take
# the text of the value we want as an argument, and leave the size in
# the appropriate variable.
#
# We discover what kind of size(1) we are using *once* and build a shell
# function named 'size_command' to wrap it. (The "function" keyword is
# redundant here, but helps me read it, so there.) Previously we were
# re-discovering the size(1) arguments three times for each test; sloooow.
#
# It is VERY IMPORTANT not to compare these numbers across platforms.
# Different size(1)'s extract section information differently. For
# example, using the native Sun size(1) and GNU size(1) built for Suns
# on the exact same binary will give very different numbers, due to all
# the variance in command-line options and arbitrary names of ELF sections.
#
# and suddenly we go to 2-space indentations...
