There are a couple of ways, callbacks and local overrides. Callbacks
are more flexible and allow upgrades to continue to occur without


In share/html/Elements/Login there are a few callbacks:

$ grep -i callback share/html/Elements/Login
% $m->callback( %ARGS, CallbackName => 'Header' );
% $m->callback( %ARGS, CallbackName => 'BeforeForm' );
%# Give callbacks a chance to add more control elements
% $m->callback( %ARGS );
% $m->callback( %ARGS, CallbackName => 'AfterForm' );
