# BackupPC: Main program for PC backups.
# DESCRIPTION
#
# BackupPC reads the configuration and status information from
-# $TopDir/conf. It then runs and manages all the backup activity.
+# $ConfDir/conf. It then runs and manages all the backup activity.
#
# As specified by $Conf{WakeupSchedule}, BackupPC wakes up periodically
# to queue backups on all the PCs. This is a four step process:
