www/p5-HTML-FillInForm 2.22 DragonFly

From README:

This module automatically inserts data from a previous HTML form into the HTML input and select tags. It is a subclass of HTML::Parser and uses it to parse the HTML and insert the values into the form tags.

One useful application is after a user submits an HTML form without filling out required field. HTML::FillInForm can be used to redisplay the HTML form with all the form elements containing the submitted info.
