+**  Initialize Users File From Passwd File
+**
+**	Everyone in AA_PASSWD is entered into the AA_USERS.  All
+**	users can access all databases.
+**
+**	User codes are assigned sequentially.  This should therefore
+**	probably be run once only, when DBS is first installed.
+**	Otherwise, usercodes can change mysteriously.
+**
+**	The optional parameter replaces the root of the DBS subtree
+**	as found in AA_PASSWD.  The DBS user must be installed
+**	(with that name) when usersetup is run.  If this parameter
+**	is a minus ("-"), output goes to the standard output.
+**
+**	The initialization file is initialized to "<home>/.ql",
+**	where <home> is the home directory in the AA_PASSWD.
