+
+### ChangeLog
+# 2003-10-20 Stein Magnus Jodal
+# - Started, but I was too tired and went home.
+#
+# 2003-10-22 Stein Magnus Jodal
+# - Continued, but I started to chat instead.
+# 
+# 2003-10-27 Stein Magnus Jodal
+# - The script started looking like something usefull.
+#
+# 2003-11-10 Stein Magnus Jodal
+# - The script can now delete old archives!
+#
+# 2004-10-17 Stein Magnus Jodal
+# - The script now creates the storagedirs if they don't exists.
+# - The delete old archives part doesn't fail if we don't have any old archives
+#   anymore. (shopt -s nullglob, so the script now requires bash)
+# - Fixed s/:/;/ at one of the lines. This made the first backup run use
+#   "full:" instead of "full" as target dir.
+#
+# 2004-10-18 Stein Magnus Jodal
+# - Fixed the calculation of $LIMIT and added a new check under the deletion
+#   part
+
+### Usage
+# skruebackup.sh -full
+# 	Run full backup
+#
+# skruebackup.sh -incr
+# 	Run incremental backup (default if the lastrun file exists)
+#
+# Example for crontab usage:
+#	0 4 1 * * /path/to/skruebackup.sh -full
+#	0 6 * * * /path/to/skruebackup.sh -incr
+
+### Vars
+# Number of archives to keep
+NUMFULL=3 # months (31 days)
+NUMINCR=40 # days
+# Dir to store the backups to
+STORAGEDIR="/backup/skrue";
+# File listing what dirs to backup
+BACKUPLIST="/home/backup/skruebackup_this.txt";
+# File touched for every backup
+LASTRUNFILE="${STORAGEDIR}/skruebackup_lastrun";
