40 dbupgrade2_tool.pl [options]
42 A validation and information tool for the database upgrade scripts
45 At startup dbupgrade2_tool.pl will always check the consistency
46 of all database upgrade scripts (e.g. circular references, invalid
47 formats, missing meta information). You can but don't have to specifiy
51 --list Lists all database upgrade tags
52 --tree Lists all database upgrades in tree form
53 --rtree Lists all database upgrades in reverse tree form
54 --graphviz[=file] Create a Postscript document showing a tree of
55 all database upgrades and their dependencies.
56 If no file name is given then the output is
57 written to 'db_dependencies.ps'.
58 --nodeps List all database upgrades that no other upgrade
60 --apply=tag Applies the database upgrades 'tag' and all
61 upgrades it depends on. If '--apply' is used
62 then the option '--user' must be used as well.
63 --help Show this help and exit.
66 --user=name The name of the user configuration to use for
67 database connectivity.
