Per-user Configuration module
==============================

	This module allows the users to set some configuration options
	on their own.  This is mainly useful for  the APOP and HomeBox
	modules, but others may benefit from this. 

	Of course,  the system  administrator can specify  the options
	which  can be  set  by the  user,  or he  might  mark them  as
	append-only. 


OPTIONS
=======

	USERCONF.CONFFILE:  The   name  of  the   configuration  file,
	relative  to the  user's  home directory.  Does  not have  any
	default. 

	USERCONF.USER_OPTIONS: A list of options that the user can set
	or override. By default, this is empty, and there is no way to
	allow a user to override all options. You have to specify each
	and every option. 

	USERCONF.USER_APPEND: A list  of append-only options. Any user
	may append a  value to any of the  options specified here, but
	he may  not override it.  If an option  does not have  a value
	when the user tries to append  to it, then the setting will be
	allowed.
