A form can be made up of several different files but must have at least on file, which contains the
HTML code used to display the form.
This file starts with the form's name followed by .form.php.
For example the main file for the
default form distributed with this script would be named default.form.php.
All form files, including the main file, are stored in the forms directory : php/SimpleContactForm/forms/
A form can also provide its own configuration, css, javascript and captcha configuration files,
all of which will be covered later on in this tutorial.
These files are also covered in the reference section.
