        <title>Two new tricks useful in proof by reflection</title>

        <description>The "Universes and Axioms" chapter has a new ending describing a way to avoid axioms in dealing with reified typing environments, and the "Proof by Reflection" chapter has a new ending explaining how to write a reification function that recurses under binders.</description>

        <description>I've moved the exercises out of the book, because I don't feel that I have the time to produce well-tested exercises yet; changed crush's use of autorewrite so that Hint Rewrite commands may be given without explicit hint databases; added a crucial new section to "More Dependent Types"; and added prose and other improvements to "Proof Search by Logic Programming."</description>

	<description>I've started passes through all chapters, with an eye toward getting ready both for <a href="http://stellar.mit.edu/S/course/6/fa11/6.892/">my fall class</a> and publication by MIT Press.  I'm adding bibliographic references, index entries, and additional exercises, along with the usual tweaks and improvements.  The version I've just put up is the result of a pass through Chapter 1.  Feedback is especially welcome now, as I get the book into final publishable shape!</description>
