Form generation in Drupal 4

Functions to enable output of HTML forms and form elements.

Drupal uses these functions to achieve consistency in its form presentation, while at the same time simplifying code and reducing the amount of HTML that must be explicitly generated by modules. See the reference at http://api.drupal.org/api/HEAD/file/developer/topics/forms_api_reference... and the quickstart guide at http://api.drupal.org/api/HEAD/file/developer/topics/forms_api.html
