  :short "Centaur Bitops Library"

  :long "<p>We provide:</p>

<ol>

<li>Some books of arithmetic theorems that augment the @(see ihs) books,</li>

<li>A @(see bitsets) library for representing finite sets of (small) natural
numbers as bitmasks, and</li>

<li>A <see topic=\"@(url sbitsets)\">sparse bitsets</see> library for
representing sets of natural numbers with lists of offset/bitmask pairs.</li>

</ol>

<h3>Loading the Library</h3>

<p>Although there is a <tt>top.lisp</tt> file, it's generally best to load only
what you actually want from the bitops library.  For arithmetic support, you
might try:</p>

<code>
 (local (include-book \"bitops/ihs-extensions\" :dir :cbooks))
 (local (include-book \"bitops/equal-by-logbitp\" :dir :cbooks))
</code>

<p>For the bitsets library:</p>

<code>
 (include-book \"bitops/bitsets\" :dir :cbooks)
</code>

<p>Or for the sparse bitsets library:</p>

<code>
 (include-book \"bitops/sbitsets\" :dir :cbooks)
</code>
