    <h1>Model 3D Validator</h1>
    <div id="jserr">Please enable JavaScript</div>
    <p>This tool provides the same functionality as <a href="https://gitlab.com/bztsrc/model3d/tree/master/m3dconv" target="new">converter</a> utility's dump feature.
    It is using the same M3D SDK in C, but compiled as WebAssembly and outputs to HTML DOM, so <em>considerably</em> slower than the native <samp>m3dconv</samp> command line tool.
    If everything went well, you should see "<samp>Model parsed OK.</samp>" as the last line of the output.</p>
    <table>
        <tr><td><samp>-d</samp></td><td>dump uncompressed chunks, do basic verification</td></tr>
        <tr><td><samp>-dd</samp></td><td>verify and dump summary of uncompressed chunks</td></tr>
        <tr><td><samp>-ddd</samp></td><td>verify and dump detailed chunk contents too</td></tr>
        <tr><td><samp>-D</samp></td><td>dump parsed, in-memory C struct representation</td></tr>
        <tr><td><samp>-v, -vv, -vvv&nbsp;&nbsp;</samp></td><td>set verbosity level of parsing (only useful with <samp>-D</samp>)</td></tr>
