+# NAME
+#     get-table-list.pl - List current and historic Zabbix database tables
+#
+# SYNOPSIS
+#     This is mainly a helper script for developing the backup script.
+#
+#     It connects to svn://svn.zabbix.com (using Subversion client "svn") and
+#     fetches the schema definitions of all tagged Zabbix versions beginning
+#     from 1.3.1 (this takes a while).
+#
+#     It then prints out a list of all tables together with the first and last
+#     Zabbix version where they were used.

+USAGE
+    $(basename "${BASH_SOURCE[*]}") [options]
+
+OPTIONS
+    -t DATABASE_TYPE
+        Database type (mysql or psql).
+        Default: $DBTYPE
+
+    -H DBHOST
+        Hostname/IP of database server (DBMS).
+        Default: $DEFAULT_DBHOST
+
+    -P DBPORT
+        DBMS port.
+        Default for mysql: 3306
+        Default for psql:  5432
+
+    -s DBSOCKET
+        Path to DBMS socket file.
+        Can be used as an alternative to specifying host (and maybe port).
+
+    -S SCHEMA
+        Name of database schema (PostgreSQL only).
+        Default: $DEFAULT_DBSCHEMA
+
+    -d DATABASE
+        Name of Zabbix database.
+        Default: $DEFAULT_DBNAME
+
+    -u DBUSER
+        DBMS user to access Zabbix database.
+        Default: $DEFAULT_DBUSER
+
+    -p DBPASSWORD
+        DBMS user password (specify "-" for a prompt).
+        Default: no password
+
+    -o DIR
+        Save Zabbix database dumps to DIR.
+        Default: $DUMPDIR
+
+    -z ZABBIX_CONFIG
+        Read database host and credentials from given Zabbix config file.
+        Default: $ZBX_CONFIG
+
+    -Z
+        Do not try to read the Zabbix server configuration.
+
+    -c MYSQL_CONFIG
+        MySQL only:
+        Read database host and credentials from given MySQL config file.
+        PLEASE NOTE:
+        The first "database" option found in the config file is used for
+        mysqldump (it needs the database to be specified via command line).
+
+    -r NUM
+        Rotate backups while keeping up to NUM generations.
+        Uses filename to match.
+        Default: keep all backups
+
+    -x
+        Compress using XZ instead of GZip.
+        PLEASE NOTE:
+        XZ compression will take much longer and consume more CPU time
+        but the resulting backup will be about half the size of the same
+        sql dump compressed using GZip. Your mileage may vary.
+
+    -0
+        Do not compress the sql dump
+
+    -n
+        Skip reverse lookup of IP address for host.
+
+    -f
+        Force backup for unknown tables / forward compatibility:
+        Don't complain about unknown tables and make a full backup of them
+
+    -i
+        Ingore unknown tables (don't include them into the backup)
+
+    -q
+        Quiet mode: no output except for errors (for batch/crontab use).
+
+    -h
+    --help
+        Show this help.
+
