+and encouragement for this release.
+This project is called \"Open Adventure\" because it's not at all clear
+how to number Adventure past 2.5 without misleading or causing
+collisions or both.  See the history file for discussion.  The
+original 6-character name on the PDP-10 has been reverted to for the
+executable in order to avoid a collision with the BSD games port of
+the ancestral 1977 version.")
