        This is the <b>Form Tools 3</b> module development documentation. Please <a href="../index_ft2/">click here</a>
        for Form Tools 2.
    </div>

    <h3>Overview</h3>

    <p>
        No script the size of Form Tools can accommodate all functionality without becoming bloated and unusable. To
        prevent this, many larger scripts turn to some form of module / plugin architecture that keeps the core
        code small, but still allows for extensibility. Form Tools is one of those scripts. Developers can
        extend the core functionality in whatever way they need without needing to tamper with the core script.
    </p>

    <p>
        The modules were structured with the following goals in mind:
    </p>

    <ul>
        <li>
            <b>Simple to install and remove</b>. Regardless of a users' technical level, nobody like fussing
            around with complicated installation instructions. If it's tough to install, people are going to give
            up, and they're likely to make mistakes - potentially causing the main script to stop working.
        </li>
        <li>
            <b>Consistent</b>. Consistency is king. Modules can't look radically different from the rest of the script
            or they've force the user doesn't have to re-learn the interface for each and every module. They need to be
            consistent so they can be translated to other languages in the same manner; consistent in the way the
            information is stored in the database and the way they tie into the core.
        </li>
        <li>
            <b>International</b>. All modules need to be able to support multiple languages.
        </li>
        <li>
            <b>Simple to develop and write</b>. Let's not forget the poor developer here! If a module isn't easy to write,
            no-one's going to want to do it.
        </li>
    </ul>

    <p>
        We've developed a modular system to allow you, the developer, to add your own functionality
        that are compatible with the above rules - just by following the required module structure.
