#NAME
#	Save - save files to a backup directory
#
#SYNOPSIS
#	Save [dir [savedir]]
#
#DESCRIPTION
#  Save all the files in the .savelist file.  The default directories
#  are /etc/ and /etc/.save/.
#
#  If there is a .savelist file, we scan it to get the list of  files
#  that  are  to  be  saved.  If not, we build the .savelist file and
#  populate it with a standard set of file names.
#
#  This is part of an on-disk backup package. It is typically run via
#  cron(1)  to  make  sure  that  valuable files are replicated.  The
#  Restore command exists to quickly restore all the files  to  their
#  backed-up states.
