1994-01-29 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* lwlib.c: Include StringDefs.h after lwlib.h.
1994-01-22 Roland McGrath (roland@churchy.gnu.ai.mit.edu)
* Makefile (xrdb-cpp.o, lwlib.o): Use $(srcdir) and file name
instead of $*.
(dispatch.o, xrdb.o, lwlib-Xm.o): Rules removed; they were
superfluous and didn't work when configured outside srcdir. The
implicit .c.o rule works fine.
1994-01-21 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* xlwmenu.c (resource_widget_value): Avoid using strdup.
1994-01-18 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* Makefile.in: New file.
* lwlib-Xolmb.c: Renamed from lwlib-Xol-mb.c.
* lwlib-Xolmb.h: Renamed from lwlib-Xol-mb.h.
* lwlib-XolmbP.h: Renamed from lwlib-Xol-mbP.h.
* lwlib-int.h: Renamed from lwlib-internal.h.

/*
* 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.

This subdirectory contains the lwlib library which provides a uniform
interface to a few different X toolkits. The library was written by Lucid.
This version has changes in the makefile to fit in with Emacs's configure
script, and some source files have been renamed to fit in 14 characters.
