-      Enter the base directory where the headers are to be found.
+      If you say 'n' here, the path below is expected to point to a directory
+      containing readily prepared headers
+      
+      If you say 'y' here, then the path below is expected to point to a
+      tarball of such a directory.
+      
+      Eg., if your headers are available in: /foo/bar/buz/my_hdrs/include,
+      say 'n' here, and enter: /foo/bar/buz/my_hdrs below.
       
-      Eg. if the headers are in /some/place/include, then enter /some/place.
-          This is the same path you entered when you typed:
-            make INSTALL_HDR_PATH=/some/place headers_install
+      Now, passing a tarball around is easier than passing a directory, so
+      if you want to, you can make a tarball of /foo/bar/buz/my_hdrs/include,
+      say 'y' here, and enter the path to this tarball below.
