+/*
+ *  If you have Motif and want to provide support for Motif widgets in lwlib,
+ *  then define USE_MOTIF.
+ *
+ *  If you have OpenLook and want to provide support for OpenLook widgets in
+ *  lwlib, then define USE_OLIT.
+ *
+ *  Otherwise, define USE_LUCID to use Lucid's own Motif-lookalike widgets,
+ *  which are included in this directory.
+ *
+ *  You cannot define USE_MOTIF and USE_OLIT at the same time, but USE_LUCID
+ *  may be defined along with either of the other two.
+ *
+ *  The OLIT menubar is slow, and possibly buggy.  We recommend against using
+ *  it unless you'd like to try to improve it (which we encourage.)
+ *
+ *  The Lucid menubar is much faster than the Motif menubar, but is missing
+ *  a few features (most notably stay-up menus and keyboard traversal.)  But
+ *  since it has the Motif look-and-feel, we recommend using it even if you
+ *  have Motif.
+ *
+ *  Currently, only the Motif widgets provide support for dialog boxes.  If
+ *  you don't have Motif, you will not be able to pop up dialog boxes from
+ *  emacs.  If you define both USE_LUCID and USE_MOTIF, then the menus will
+ *  be implemented with Lucid widgets, and the dialog boxes will be 
+ *  implemented with Motif widgets.
+ *
+ *  It shouldn't take much work to add support for non-Motif dialog boxes;
+ *  all that one need do is add code that implements Athena versions of the 
+ *  xm_create_dialog(), xm_update_one_widget(), and xm_update_one_value()
+ *  routines in lwlib-Xm.c.  If you do this, please send us the code.
+ *
+ *  If you have your X11 source tree online, then you should define 
+ *  INCLUDE_EXTENSIONS to cause this library to contain some useful functions
+ *  which Xt should provide but doesn't.  You can only do this if you have
+ *  the source tree online, because these functions require access to internal
+ *  Xt data structures that are not defined in the exported header files.
+ *  If you define INCLUDE_EXTENSIONS, then the variable $TOP must point at the
+ *  root of the X11 source tree.
+ *
+ *  To build a "shared" version of lwlib as well, define BUILD_SHARED_LIB.
+ *  If INCLUDE_EXTENSIONS is defined, and you want to link with a dynamic
+ *  version of Xt, it may be necessary to build a shared version of lwlib as
+ *  well, as the X libraries sometimes put *different code* in the dynamic
+ *  and shared versions of their libraries, for some reason I don't understand.
+ *
+ *  Remember, if you build and install a shared version of lwlib, you may need
+ *  to run ldconfig(8) before anything will realize that it exists.
+ *
+ *  To compile with support for Lucid's Energize Programming System, you must
+ *  define all of ENERGIZE, USE_LUCID, USE_MOTIF, and INCLUDE_EXTENSIONS.
