# sed script to post-process Emissary's -nametree output for snmptalk.
# In an ideal world where we didn't have to worry about backwards compatability,
# we'd just make these changes in the compiler, but it's not worth generating a
# new release of Emissary just to support one demo program, so for now we just
# post-process Emissary's output.
#
# Ordinarily, snmptalk reads a file called mib.rt to get the MIB definitions.
# This doesn't work so well on an embedded system where we may not have a
# filesystem, so we fall back to the way snmptalk worked back in the dawn of
# time, and just compile in all the MIB information.  This script just brings
# the old static output format up to snmptalk's current expectations.
#
# This script works on all the versions of sed where we've tried it.
# Rumor has it that some versions of sed are so abysmally stupid that
# they will only tolerate a single comment on the first line of a script.
# If you get weird errors trying to use this script, try deleting all the
# comments to see if that helps....
