 ** General
+    Much general information is in INSTALL.  If it's covered in
+    INSTALL, we don't repeat it here.
+
+*** How does I configure to get the buffer tabs/progress bars?
+
+These features depend on support for "native widgets".  Use the
+--with-widgets option to configure.  Configuration of widgets is
+automatic for "modern" toolkits (MS Windows, GTK, and Motif), but if
+you are using Xt and the Athena widgets, you will probably want to
+specify a "3d" widget set.  See configure --usage, and don't forget to
+install the corresponding development libraries.
+
+*** I know I have libfoo installed, but configure doesn't find it.
+
+Typical of Linux systems with package managers.  To link with a shared
+library, you only need the shared library.  To compile objects that
+link with it, you need the headers---and distros don't provide them with
+the libraries.  You need the additional "development" package, too.

 *** Don't use -O2 with gcc 2.8.1 and egcs 1.0 under SPARC architectures
 without also using `-fno-schedule-insns'.
