   Methods
       new ( $type, [ key => value, ... ] )
           Constructor.  Creates new instance of Sympa::Aliases.

           Returns one of appropriate subclasses according to $type:

           'none'
               No aliases management.

           Full path to executable
               Use external program to manage aliases.  See Sympa::Aliases::External.

           Name of subclass
               Use a subclass "Sympa::Aliases::name" to manage aliases.

           For invalid types returns "undef".

           Optional "key => value" pairs are included in the instance as hash entries.

       check ($listname, $robot_id)
           Instance method, overridable.  Checks if the addresses of requested list exist
           already.

               List's robot.

           Returns:

           True value if one of addresses exists.  0 if none found.  "undef" if something wrong
           happened.

           By default, this method always returns 0.

           Returns:

           1 if installation succeeded.  0 if there were no aliases to be installed.  "undef" if
           not applicable.

           By default, this method always returns 0.

       del ($list)
           Instance method, overridable.  Removes aliases for the list $list.

           Parameters:
