[Ben Sgro (ProjectSkyLine)]

Hello Kenneth,

I saw an example similiar to this on PHP.net. I don't really
see why try/catch is better ... Not trying to start a war here. -= ]

function try_include( $filename )
{
    if( include($filename) != 1 )
    {
        echo "Problem trying to include file!";
        return false;
     }
    return true;
}
