-# Boost.Integer
-
-Boost.Integer, part of collection of the [Boost C++ Libraries](https://github.com/boostorg), provides
-integer type support, particularly helpful in generic programming. It provides the means to select
-an integer type based upon its properties, like the number of bits or the maximum supported value,
-as well as compile-time bit mask selection. There is a derivative of `std::numeric_limits` that provides
-integral constant expressions for `min` and `max`...
-Finally, it provides two compile-time algorithms: determining the highest power of two in a
-compile-time value; and computing min and max of constant expressions.
-
-### Directories

-* **doc** - QuickBook documentation sources
-* **include** - Interface headers of Boost.Integer
-* **test** - Boost.Integer unit tests

-### More information
-
-* [Documentation](https://boost.org/libs/integer)
-* [Report bugs](https://github.com/boostorg/integer/issues/new). Be sure to mention Boost version, platform and compiler you're using. A small compilable code sample to reproduce the problem is always good as well.
-* Submit your patches as pull requests against **develop** branch. Note that by submitting patches you agree to license your modifications under the [Boost Software License, Version 1.0](https://www.boost.org/LICENSE_1_0.txt).

+        The <code class="literal">int_fast_t</code> class template maps its input type to the

+        a bunch of <code class="literal">char</code> objects may go faster if they were converted
+        to <code class="literal">int</code> objects before processing. The input type, passed

+        The base-two (binary) logarithm, abbreviated lb, function is occasionally
+        used to give order-estimates of computer algorithms. The truncated logarithm
+        can be considered the highest power-of-two in a value, which corresponds
+        to the value's highest set bit (for binary integers). Sometimes the highest-bit
+        position could be used in generic programming, which requires the position
+        to be available statically (<span class="emphasis"><em>i.e.</em></span> at compile-time).

+<p>
+      Boost.Integer provides integer type support, particularly helpful in generic
+      programming. It provides the means to select an integer type based upon its
+      properties, like the number of bits or the maximum supported value, as well
+      as compile-time bit mask selection. There is a derivative of std::numeric_limits
+      that provides integral constant expressions for <code class="computeroutput"><span class="identifier">min</span></code>
+      and <code class="computeroutput"><span class="identifier">max</span></code>. Finally, it provides
+      two compile-time algorithms: determining the highest power of two in a compile-time
+      value; and computing min and max of constant expressions.

-[section:mod_inverse Modular Multiplicative Inverse]
-
-[section Introduction]
-
-The modular multiplicative inverse of a number /a/ is that number /x/ which satisfies /ax/ = 1 mod /p/.
-A fast algorithm for computing modular multiplicative inverses based on the extended Euclidean algorithm exists and is provided by Boost.
-
-[endsect]

-[section Synopsis]
-
-    #include <boost/integer/mod_inverse.hpp>
-
-    namespace boost { namespace integer {
-
-    template<class Z>
-    Z mod_inverse(Z a, Z m);
-
-    }}
-
-[endsect]
-
-[section Usage]
-
-    int x = mod_inverse(2, 5);
-    // prints x = 3:
-    std::cout << "x = " << x << "\n";
-
-    int y = mod_inverse(2, 4);
-    if (y == 0)
-    {
-        std::cout << "There is no inverse of 2 mod 4\n";
-    }
-
-Multiplicative modular inverses exist if and only if /a/ and /m/ are coprime.
-If /a/ and /m/ share a common factor, then `mod_inverse(a, m)` returns zero.
