-      ECB stands for "Emacs Code Browser".  While Emacs already has
-      good editing support for many modes, its browsing support is
-      somewhat lacking.  That's where ECB comes in: it displays a
-      number of informational windows that allow for easy source code
-      navigation and overview.
