- *  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.
