+// Pictures to show why I prefer the symmetric BPKI model.  As far as
+// I can tell, the asymmetric model is every bit as complex for me as
+// the symmetric model; the only difference is the added annoyance of
+// having to keep track of a larger number of BSC EE certificates.
+//
 // Color code:
-//   Black: hosting entity
-//   Blue:  hosted entity
-//   Red:   cross-certified peer
+//   Black:	Hosting entity
+//   Blue:	Hosted entity
+//   Red:	Cross-certified peer
 //
 // Shape code:
-//   Octagon: TA
-//   Diamond: CA
-//   Record:  EE
+//   Octagon:	TA
+//   Diamond:	CA
+//   Record:	EE
