function help()
{
    global $this_script;

    ?>
Access Control List command line tool.

This script must be run in the common site directory (i.e. the parent
directory of the document root). DB credentials are retrieved from:
global/db_auth.inc.php so this file must exist. Further more this script
must be executed as the owner of the db_auth.inc.php file.

Three types of objects are managed by this interface: ARO - Access
Request Objects, ACO - Access Control Objects, and AXO - Access Xtra
Objects. These are most often used as a USER -> ACTION -> OBJECT model,
but can just as easily be SPICES -> CUISINES -> DISHES A privilege is
allowed if a user (ARO) can perform an action (ACO) on something (AXO).
For example, Bob can edit article 4. If the AXO if omitted, this becomes
"Bob can edit" (period).

Each access object is stored as a node in hierarchical tree structures. A
permission granted to a node is applied to all its children. If a child
node is specified a different permission that is more specific that
anything on the branch it will take precedence. If no permission is
specified, root is used for that object. Root, in this case, means
"anything" since it is at the top of all branches.

Usage: <?php echo $this_script; ?> command [args]

Where command is any of the following (with arguments):
    
    initdb
    list [aro | aco | axo | all | perms]
    check aro [aco] [axo]
    addaro aro [parent]
    addaco aco [parent]
    addaxo axo [parent]
    mvaro aro [parent]
    mvaco aco [parent]
    mvaxo axo [parent]
    rmaro aro
    rmaco aco
    rmaxo axo
    grant aro [aco] [axo]
    revoke aro [aco] [axo]
    delete [aro] [aco] [axo]
    

For the add*, mv*, grant, and revoke commands if any of the optional 
args are not provided, 'root' is assumed. For the delete command 
'null' is considered a wild-card to delete all objects of that type.
