+;;;; Computing the default load-path, etc.
+;;;
+;;; This stuff is a complete mess and isn't nearly as general as it 
+;;; thinks it is.  It should be rethunk.  In particular, too much logic
+;;; is duplicated between the code that looks around for the various
+;;; directories, and the code which suggests where to create the various
+;;; directories once it decides they are missing.
+
+;;; The source directory has this layout:
+;;;
+;;;    BUILD_ROOT/src/xemacs*			  argv[0]
+;;;    BUILD_ROOT/xemacs*			  argv[0], possibly
+;;;    BUILD_ROOT/lisp/
+;;;    BUILD_ROOT/etc/				  data-directory
+;;;    BUILD_ROOT/info/
+;;;    BUILD_ROOT/lib-src/			  exec-directory, doc-directory
+;;;    BUILD_ROOT/lock/
+;;;
+;;; The default tree created by "make install" has this layout:
+;;;
+;;;    PREFIX/bin/xemacs*	  		argv[0]
+;;;    PREFIX/lib/xemacs-VERSION/lisp/
+;;;    PREFIX/lib/xemacs-VERSION/etc/		  data-directory
+;;;    PREFIX/lib/xemacs-VERSION/info/
+;;;    PREFIX/lib/xemacs-VERSION/CONFIGURATION/	  exec-directory, doc-directory
+;;;    PREFIX/lib/xemacs/lock/
+;;;    PREFIX/lib/xemacs/site-lisp/
+;;;
+;;; The binary packages we ship have that layout, except that argv[0] has
+;;; been moved one level deeper under the bin directory:
+;;;
+;;;    PREFIX/bin/CONFIGURATION/xemacs*
+;;;
+;;; The following code has to deal with at least the above three situations,
+;;; and it should be possible for it to deal with more.  Though perhaps that
+;;; does cover it all?  The trick is, when something is missing, realizing
+;;; which of those three layouts is mostly in place, so that we can suggest
+;;; the right directories in the error message.
