# Basic recognition of Digital UNIX core dumps - Mike Bremford <mike@opac.bl.uk>
#
# The actual magic number is just "Core", followed by a 2-byte version
# number; however, treating any file that begins with "Core" as a Digital
# UNIX core dump file may produce too many false hits, so we include one
# byte of the version number as well; DU 5.0 appears only to be up to
# version 2.
