          <p>This document gives an overview of some FreeType&nbsp;2
            internals.  Read this carefully if you want to understand
            the innards of the library in order to hack or extend
            it.</p>

<p>Note that many, quite important details are still
            missing, which are hopefully addressed in the not too
            distant future.  Volunteers to help with this task are
            highly welcomed!</p>
