I intend to orphan the open-adventure package. After reading a list
called "Weird little guys of FOSS"[1], I found the author of
open-adventure on that list. I don't want to maintain this software anymore.

The package description is:
 This is the last descendent of the original 1976 Colossal Cave
 Adventure worked on by the original authors -- Crowther & Woods.
 It has sometimes been known as Adventure 2.5. The original PDP-10
 name 'advent' is used for the built program to avoid collision with
 the BSD Games version.
