Glk has been a work of many years and many people. If I tried to list everyone who has offered comments and suggestions, I would immediately go blank, forget everyone's name, and become a mute hermit-like creature living in a train tunnel under Oakland. But I must thank those people who have written Glk libraries and linking systems: Matt Kimball, Ross Raszewski, David Kinder, John Elliott, Joe Mason, Stark Springs, and, er, anyone I missed. Look! A train!

Evin Robertson wrote the original proposal for the Glk Unicode functions, which I imported nearly verbatim into this document. Thank you.
