+      (description "This is a system implementing an advanced dialogue system
+that is capable of complex dialogue flow including choice trees and
+conditional branching.  Speechless was first developed for the
+\"Kandria\" (@url{https://kandria.com}) game, and has since been separated and
+made public in the hopes that it may find use elsewhere or inspire other
+developers to build similar systems.
+
+Speechless is based on the
+\"Markless\" (@url{https://shirakumo.github.io/markless}) document standard
+for its syntax and makes use of Markless' ability to be extended to add
+additional constructs useful for dialogue systems.
+
+Speechless can compile dialogue from its base textual form into an efficient
+instruction set, which is then executed when the game is run.  Execution of the
+dialogue is completely engine-agnostic, and only requires some simple
+integration with a client protocol to run.
+
+Thanks to Markless' extensibility, Speechless can also be further extended to
+include additional syntax and constructs that may be useful for your
+particular game.")
