+   This structure sort of takes the place of global variables or perhaps
+is the global variable.  (It can be accessed globally as ps_global.  One
+advantage to this is that as soon as you see a reference to the structure
+you know it is a global variable. 
+   In general it is treated as global by the lower level and utility
+routines, but it is not treated so by the main screen driving routines.
+Each of them receives it as an argument and then sets ps_global to the
+argument they received.  This is sort of with the thought that things
+might be coupled more loosely one day and that Pine might run where there
+is more than one window and more than one instance.  But we haven't kept
+up with this convention very well.
