#  this script puts the files output from protocmp into 
#  the release packages.
#   
#  usage:  package input_filename output_filename
#
#  the input_filename is the output file from the script protocmp.
#  the output_filename will list packages and filenames.
#
#  package attempts to mount /tarfiles.
#  you should have an entry for /tarfiles in your fstab, eg:
#
#    werewolf:/tarfiles        /tarfiles   nfs ro,soft,bg,intr,noauto 0 0
#
#  steps:
#    make sure /tarfiles are mounted
#    search for lines in the input file beginning with obsolete, new, different
#    skip lines beginning with obsolete
#    strip off beginning of filename (/usr, /usr/kvm)
#    search /tarfiles/sun4c/packages for the file 
#    write the file name out to stdout 
#    check for any files that can't be assigned to a package
