## Using something HTMLgen-ish:

defaults = {'username': req.cookie('username', '')}
defaults.update(req.fields)

if request.fields.get('username'):
     defaults['message'] = html.b("Login incorrect") + html.br()

defaults['action'] = '/loginform'

form = html.form(action=defaults['action'], method="POST")(
     defaults.get('message'),
     'Username: ',
     html.input(type="text", name="username", 
value=defaults.get('username')),
     html.br(),
     'Password: ',
     html.input(type="password", name="password", 
value=defaults.get('password')),
     html.input(type="submit"))
