+= README for Open Adventure =
+
+This code is a forward-port of the Crowther/Woods Adventure 2.5 from
+1995, last version in the main line of Colossal Cave Adventure
+development written by the original authors. The authors have given
+permission and encouragement to this release.
+
+The file history.txt contains a more detailed history of this game
+and its ancestors.
+
+This project is called "Open Adventure" because it's not at all clear
+to number Adventure past 2.5 without misleading or causing collisions
+or both. See the history file for discussion.
