<h1>Transcode - overview of libraries</h1>

<div id="summary">
<h3>Summary</h3>
<p>
As part of 1.1.0 development cycle, an huge internal reorganization
effort has undergone. Reorganization isn't yet (as 1.1.0 released)
complete, and will involve every component in transcode codebase.
This document provide an overview of reorganized internal transcode
libraries, internal dependencies and purposes.
</p>
<h4>General Warning:</h4>
<p>
transcode libraries are quite carefully designed and implemented
in order to be independent, self contained as much as is possible,
but they <strong>are not</strong> intended to be easily separated by transcode
codebase and to be used in external projects. <strong>We don't care too
much about API/ABI stability yet, and we don't do testing on
this direction</strong>. Help us to improve code, or use it at own risk :)
