# I am *not* going to create separate packages for each of the individual
# tools, as some distros do. They're small enough that it's worth the
# tiny bit of extra disk space for unused tools, to avoid the annoyances
# of having to write and test 10 or 12 packages. For the same reason,
# the firmware is being included in the package as well.
# *** I agree.  --rworkman   :-)
