+
+<p>
+Frotz is an interpreter for Infocom games and other Z-machine games. It
+complies with
+<a href="http://www.inform-fiction.org/zmachine/index.html">standard 1.0</a>
+of Graham Nelson's specification. It was written by Stefan Jokisch in
+1995-1997. It was ported to Unix by Galen Hazelwood. Currently the Unix
+port is being developed and maintained by David Griffith. The Unix port
+is also the canonical core version upon which all other ports are based.

+<h2><a name="credits">Credits</a></h2>
+<p>
+This program started as a remake of Mark Howell's Zip, but has grown into
+a completely new interpreter with ports for lots of platforms.
+
+<p>
+Thanks goes to Stefan Jokisch for writing Frotz and Galen Hazelwood for
+doing the initial work of porting it to Unix. Thanks also to Jim Dunleavy
+for his optimization to the core Frotz code. Other people to thank
+include those who uploaded patches to Unix Frotz to the IF-Archive and
+getting me interested in the inner-workings of interpreters like Frotz,
+people who posted to Usenet feedback on what I was doing, testers, those
+who donated the use of machines for porting, sent me patches, etc. These
+include, but are not limited to:
+
+<blockquote>
+Torbjorn Anderson, Timo Korvola, Martin Frost, Mihail Milushev, David
+Picton, Chris Sullivan, Leonard Richardson, Stephen Kitt, Paul E Coad,
+Paul Janzen, Brad Town, Jason C Penney, Denis Hirschfeldt, Jacob Nevins,
+Matteo De Luigi, Steven Frank, Thomas Troeger, and others that I've
+forgotten.
+</blockquote>
+
+<p>
+Michael Edmonson (author of Rezrov) and Evin Robertson (author of Nitfol)
+deserve recognition for the ideas that I've borrowed from their
+programs. Al Petrofsky (creator of dumbfrotz) donated much code to allow
+Unix Frotz to semi-support V6 games.
