+;; This instance of PG is handy just for using script management to
+;; cut-and-paste into a buffer running an ordinary shell of some kind.
+;;
+;; I'm providing this so that tool demonstrators may use it instead of
+;; tediously doing cut-and-paste of commands from a file.  Nothing
+;; to do with theorem proving really!
+;;
+;; To use this instance of PG, visit a file with the ".pgsh" extension.
+;; 
+;; Feedback welcome.
