Scott James Remnant 0550115589 Further sweeping changes to the user interface to libtool from 
`configure.ac' to allow users to better control the list of
supported languages.  Three LT_INIT options 'no-lang', 'all-lang'
and 'auto-lang' (the default) control the initial list and others
may be added with LT_LANG.

* m4/libtool.m4 (_LT_CONFIG): Renamed AC_LIBTOOL_CONFIG to _LT_CONFIG
which is more consistent with our own namespace and gets us further out
of Autoconf's.
(_LT_LIBTOOL_TAGS): Output available_tags variable based entirely
on the value of _LT_TAGS.
(_LT_COPYING): Call _LT_LIBTOOL_TAGS to output available tags,
always append tag configuration if the tag is available.
(LT_LANG): New macro to enable support for a language that accepts
tag names (eg. "CXX") or human language names (eg. "C++").
(_LT_LANG): Internal support macro for above that appends the
tag to _LT_TAGS and calls the appropriate config macro.
(LT_INIT): Ensure that LT_LANG is not called before LT_INIT.
(AC_LIBTOOL_TAGS): Removed, call LT_LANG for each language now.
(_LT_AC_TAG_CHECK): Removed, _LT_LANG handles duplicate calls.
(_LT_LANG_DEFAULT_CONFIG): Macro to set initial language support
based on options passed to LT_INIT.
(_LT_SETUP): Call _LT_LANG_DEFAULT_CONFIG.
(_LT_AC_TAG_CONFIG): Removed, handled by _LT_LANG_DEFAULT_CONFIG.
(_LT_AC_LANG_CXX, _LT_AC_LANG_F77, _LT_AC_LANG_GCJ): Removed,
automatic language support inclusion now handled by
_LT_LANG_DEFAULT_CONFIG.
(AC_LIBTOOL_CXX): Obsolete macro, update to LT_LANG(C++).
(AC_LIBTOOL_F77): Obsolete macro, update to LT_LANG(Fortran 77).
(AC_LIBTOOL_GCJ): Obsolete macro, update to LT_LANG(Java).
(AC_LIBTOOL_LANG_C_CONFIG_: Removed.
(_LT_AC_LANG_C_CONFIG): Renamed to _LT_LANG_C_CONFIG, call
_LT_CONFIG instead of AC_LIBTOOL_CONFIG.
(_LT_SETUP): Replace call to AC_LIBTOOL_LANG_C_CONFIG with call to
new _LT_LANG_C_CONFIG macro.
(AC_LIBTOOL_LANG_CXX_CONFIG): Removed.
(_LT_AC_LANG_CXX_CONFIG): Renamed to _LT_LANG_CXX_CONFIG, call
_LT_CONFIG instead of AC_LIBTOOL_CONFIG.
(AC_LIBTOOL_LANG_F77_CONFIG): Removed.
(_LT_AC_LANG_F77_CONFIG): Renamed to _LT_LANG_F77_CONFIG, call
_LT_CONFIG instead of AC_LIBTOOL_CONFIG.
(AC_LIBTOOL_LANG_GCJ_CONFIG): Removed.
(_LT_AC_LANG_GCJ_CONFIG): Renamed to _LT_LANG_GCJ_CONFIG, call
_LT_CONFIG instead of AC_LIBTOOL_CONFIG.
(AC_LIBTOOL_LANG_RC_CONFIG): Removed.
(_LT_AC_LANG_RC_CONFIG): Renamed to _LT_LANG_RC_CONFIG, call
_LT_CONFIG instead of AC_LIBTOOL_CONFIG.
(LT_AC_PROG_GCJ): Renamed to LT_PROG_GCJ.
(LT_AC_PROG_RC): Renamed to LT_PROG_RC.
* m4/ltoptions.m4: Define new 'no-lang', 'auto-lang' and 'all-lang'
options which set the default for _LT_LANG_DEFAULT_CONFIG.
* m4/lt~obsolete.m4: Removed AC_LIBTOOL_CONFIG, _LT_AC_LANG_C_CONFIG,
_LT_AC_LANG_GCJ_CONFIG, _LT_AC_LANG_RC_CONFIG; all of which are no
long referenced in any way.
* configure.ac: Enable all languages.
* tests/cdemo/configure.ac, tests/demo/configure,ac,
tests/depdemo/configure.ac, tests/f77demo/configure.ac,
tests/mdemo/configure.ac, tests/pdemo/configure,ac,
tests/tagdemo/configure.ac: Remove calls to AC_LIBTOOL_TAGS,
the default 'auto-lang' mode now does the right thing.
* doc/libtool.texi (The LT_INIT macro): Add documentation for
new LT_INIT options and the LT_LANG macro, replacing the old
documentation of AC_LIBTOOL_TAGS which is no more.
* NEWS: Updated.

README 

This is mdemo, an example package that uses GNU libtool with an
Automake-generated environment to build two simple modules and 
a program.

It demonstrates how to build both dynamic and static libraries
that can be dlopened. mdemo uses libtool's portable dlopen
wrapper called "libltdl". 
All exported symbols are prefixed with "libname_LTX_" to avoid
symbols conflicts, especially when linking statically.
libltdl will automatically cut the prefix off to get the real name.

Note that on Windows, for the purposes of illustrating ltdl, the
libraries *are* built as dll's, but do not have the __declspec
machinery to make them suitable for loading at link time.  This is
only for clarity inside this example, look at the example in ../demo
to see how the __declspec macros should be set up.
