<h1 align="center">
Fossil Delta Encoding Algorithm
</h1>
<h2>Abstract</h2>

<p>A key component for the efficient storage of multiple revisions of
a file in fossil repositories is the use of delta-compression, i.e. to
store only the changes between revisions instead of the whole
file.</p>

<p>This document describes the encoding algorithm used by Fossil to
