<div class="paragraph"><p>The <a href="http://www.smlnj.org/doc/ckit">ckit Library</a> is a C front end
written in SML that translates C source code (after preprocessing)
into abstract syntax represented as a set of SML datatypes.  The ckit
Library is distributed with SML/NJ.  Due to differences between SML/NJ
and MLton, this library will not work out-of-the box with MLton.</p></div>
<div class="paragraph"><p>As of 20200718, MLton includes a port of the ckit Library synchronized
with SML/NJ version 110.98.</p></div>
