The goal of CGI::FormBuilder (FormBuilder) is to provide an easy way for you to generate and process entire CGI form-based applications. Its main features are:

Field Abstraction
Viewing fields as entities (instead of just params), where the HTML representation, CGI values, validation, and so on are properties of each field.

DWIMmery
Lots of built-in "intelligence" (such as automatic field typing), giving you about a 4:1 ratio of the code it generates versus what you have to write.

Built-in Validation
Full-blown regex validation for fields, even including JavaScript code generation.

Template Support
Pluggable support for external template engines, such as HTML::Template, Text::Template, Template Toolkit, and CGI::FastTemplate.

Plus, the native HTML generated is valid XHTML 1.0 Transitional.
