>Groups allow the administrator
    to isolate bugs or products that should only be seen by certain people.
    There are two types of group - Generic Groups, and Product-Based Groups.
    </P
><P
>&#13;    Product-Based Groups are matched with products, and allow you to restrict
    access to bugs on a per-product basis. They are enabled using the 
    usebuggroups Param. Turning on the usebuggroupsentry
    Param will mean bugs automatically get added to their product group when 
    filed.   
    </P
><P
>&#13;    Generic Groups have no special relationship to products; 
    you create them, and put bugs in them
    as required. One example of the use of Generic Groups 
    is Mozilla's "Security" group,
    into which security-sensitive bugs are placed until fixed. Only the
    Mozilla Security Team are members of this group.

>XXX is this still true?
          "usebuggroupsentry" has the capacity to prevent the
          administrative user from directly altering bugs because of
          conflicting group permissions. If you plan on using
          "usebuggroupsentry", you should plan on restricting
          administrative account usage to administrative duties only. In
          other words, manage bugs with an unpriveleged user account, and
          manage users, groups, Products, etc. with the administrative
          account.</P

>In future, when you create a Product, a matching group will be
        automatically created. If you need to add a Product Group to
        a Product which was created before you turned on usebuggroups,
        then simply create a new group, as outlined above, with the
        same name as the Product.</P
