# Usage: mibfetch [ -d outdir ] host directory rfc [mibs]
#
# If "rfc" contains a "." it is expected to be a complete file name,
# otherwise it is assumed to be just the rfc number.
# If "mibs" is specified, it is a ":" separated list of mibs to extract,
# otherwise all mibs are extracted.
#
# The script fetches the file from the givn directory on the given
# host, and then runs the file through smistrip to extract the mibs.
