+dbupgrade2_tool.pl [options]
+
+  A validation and information tool for the database upgrade scripts
+  in 'sql/Pg-upgrade2'.
+
+  At startup dbupgrade2_tool.pl will always check the consistency
+  of all database upgrade scripts (e.g. circular references, invalid
+  formats, missing meta information). You can but don't have to specifiy
+  additional actions.
+
+  Actions:
+    --list               Lists all database upgrade tags
+    --tree               Lists all database upgrades in tree form
+    --rtree              Lists all database upgrades in reverse tree form
+    --graphviz[=file]    Create a Postscript document showing a tree of
+                         all database upgrades and their dependencies.
+                         If no file name is given then the output is
+                         written to 'db_dependencies.ps'.
+    --nodeps             List all database upgrades that no other upgrade
+                         depends on
+    --apply=tag          Applies the database upgrades 'tag' and all
+                         upgrades it depends on. If '--apply' is used
+                         then the option '--user' must be used as well.
+    --help               Show this help and exit.
+
+  Options:
+    --user=name          The name of the user configuration to use for
+                         database connectivity.
