+SYNOPSIS
+        #include <sys/driver_hooks.h>
+
+        set_driver_hook(H_COMMAND, value)
+
+        <value> being:
+
+          int <closure>(string command, object command_giver)
+          int <name>(string command, object command_giver)
+
+DESCRIPTION
+        Optional hook to parse and execute commands. If this hook is
+        used, it bypasses the normal command parsing done by the
+        driver (including the MODIFY_COMMAND and NOTIFY_FAIL hooks).
+
+        The hook is called with two parameters: the command received
+        from the living (interactive user or NPC), and the living
+        object (the 'command giver') itself. The hook has to return
+        non-0 if the command was found and executed, and 0 otherwise.
+
+        At the time the hook is called, query_command() returns the
+        command string and this_player() returns the living object.
+        query_verb() and query_notify_fail() return 0.
+
+        If the hook is a string, it is the name of an lfun in the
+        command giver; if the hook is a lambda closure, it is bound to
+        the command giver before the call.
