#  bug.chk [arch]
#
#   This uses publically available (available via anon-ftp from 
# cert.sei.cmu.edu) data to determine if a security bug is present.  It
# checks the date of the program in question against the cert advisory
# date, and, if it is older than that, it flags it as a potential
# bug/vulnerability.
#
#  Right now, it either uses your argument as an archetecture type, or
# tries to figure out what kind of platform you're running
# on, and then looks at the bugs known for your host, in a file named
# "bug.chk.arch_type".
