+<h1>libtfm</h1>
+
+<p>This is a trivial port of the Tom's Fast Math (TFM) bignum library to
+the Cryptech environment. We use a git submodule to pull the package
+from GitHub, we verify that the SHA-256 digest of what we got from
+GitHub matches the version we tested, then we build the library with
+the options we want.</p>
+
+<p>See tomsfastmath/doc/tfm.pdf for API details.</p>
+
+<p>In theory, the need for most (perhaps all) of this will go away when
+more of the bignum math is implemented in Verilog. Part of the reason
+for using the TFM library is that its extremely modular structure make
+it easy for us to link in only the functions we need.</p>
