+System configuration:
+
+	IBM RS/6000 running AIX v4.2 or newer
+
+Latest Icon version:
+
+	Version 9.4.1
+
+Installer:
+
+	Gregg Townsend
+	Icon Project
+	The University of Arizona
+
+Missing features:
+
+	None
+
+Known bugs:
+
+	None
+
+Comments:
+
+	Tested on an RS/6000 running AIX 4.3.
+
+	AIX Version 4.2 or newer is needed for loadfunc().
+	Although loadfunc() is enabled, I've never succeeded in
+	building a loadable library that it finds acceptable.
