#
# Read the README file!
#
# The basic idea is that we create two output files, one containing
# the files that will stay, and the other listing the files that
# will be pulled from the host (ie. not go into the appliance now).
#
# The list of files that stay ('supermin.incfiles') is just a straight
# list of files and directories.
#
# The list of files that come from the host ('*.supermin.hostfiles')
# can include wildcards, to allow libraries to be upgraded on the
# host.
