NEWS

+New in 0.6a:
+* Total rewrite of libtool, along with a new model for library building.
+* Updated documentation for the new paradigm.
+* Proper handling of broken system linkers, such as the ones on AIX
+  and HP-UX.
+* configure mode is now a separate program, `ltconfig'
+* Libtool only supports `compile', `link', and `install' modes, via
+  the `--mode' command line option.
+* Automatic mode guessing, based on the command line.
+
+New in 0.6: (never released)
+* Optimization to cut `libtool archive' execution time by a factor of 5.
+* New AM_REPLACE_FUNCS macro to generate LTLIBOBJS as well as LIBOBJS.
+  From Karl Berry.
+* Renamed ABOUT-LIBS to ABOUT-LIBTOOL.  From Karl Berry.
+* Include the generated libtool script in the distribution.
+* Quote metacharacters in arguments to `libtool compile'.
+* Bug fixes.
+* Removed `link' and `install-progs' modes because they cannot be 
+  correctly implemented.  See (libtool)Linking Against Pseudo-Libraries.
+
+New in 0.5:
+* Disabled install-progs until next version, when it will be correctly
+  implemented.
+* Clearer library versioning documentation.  See (libtool)Versioning.
+* Renamed gm_PROG_LIBTOOL to AM_PROG_LIBTOOL
+* Libtool now creates pseudo-objects named foo.lo and pseudo-archives named
+  libfoo.la instead of foo.o and libfoo.a.  See the documentation.
+* libtool compile doesn't interfere with user CFLAGS if they don't
+  conflict with the current objtype.  From Karl Berry.
+* Created new libinfo helper script.
+* libversion.in files are obsolete -- libtool uses libinfo to read the
+  new LIBINFO files.
+* Libtool is better at finding its config file and helper scripts.
+* Support for *-*-gnu*
+
+New in 0.4:
+* Bug fixes and new regression tests
+* On unsupported configurations, ``libtool configure'' demotes OBJTYPES to
+  `standard' instead of aborting
+* Added new object type, `t', for tcov(1) support
+* Support for *-*-aix3*, *-*-aix4*, *-*-hpux10*, *-*-osf3*, and *-*-solaris2*
+
+New in 0.3:
+* Bug fixes and new regression tests
+* Added new uninstall-libs mode
+* Added a host argument to configure mode
+* Fixed debugging/hyper-optimizing flags conflict (from Karl Berry)
+* Support for --no-whole-archive when needed by GNU ld (from Ulrich Drepper)
+* Implementation of --enable-linktype, --enable-profile, --enable-shared,
+  --enable-static in gm_PROG_LIBTOOL macro
+* New `libtoolize' program (modeled after GNU gettext's `gettextize') to help
+  conversion to libtool
+* New ABOUT-LIBS document for inclusion with libtool-supported packages
+
+New in 0.2:
+* Support for *-*-linux
+* Better checking for GNU ld
+* Reimplemented the config file so that it corresponds more closely to the
+  variables listed in (libtool)Porting Libtool.
+* Reimplemented the shared library version scheme.  See (libtool)Versioning.
+* Replaced `--config-file' and `--version-file' options with `--confdir'
+* Added new install-libs and install-progs modes
+
+New in 0.1:
+* First release of libtool
+* Support for: *-*-freebsd*, *-*-netbsd*, *-*-sunos4*, *-*-ultrix4*

+This is GNU libtool, a generic library support script.  Libtool hides
+the complexity of generating special library types (such as shared
+libraries) behind a consistent interface.
+
+To use libtool, add the new generic library building commands to your
+Makefile, Makefile.in, or Makefile.am.  See the documentation for
+details.
+
+Libtool supports building static libraries on all platforms.
+
+Shared library support has been implemented for these platforms:
+  NetBSD 1.x (*-*-netbsd*)
+
+See the file NEWS for a description of recent changes to libtool.
+
+See the file INSTALL for instructions on how to build and install libtool.
+
+If you have any suggestions or bug reports, or you wish to port libtool
+to a new platform, please send electronic mail to Gord Matzigkeit
+<gord@gnu.ai.mit.edu>.

+* Find link_static_flag for every C compiler, currently at least
+native cc's for AIX, HP-UX, OSF/1.
+
+* Configure test for a library-stripping program (strip -x on NetBSD)
+
+* Implement fuller support for profiled libraries (libNAME_p), and
+resolve naming difficulties for debuggable libraries (libNAME_g on
+Linux at least), old system 5 shared libraries (libNAME_s), etc.
+
+* We should use the C compiler rather than the linker to create shared
+libraries, if at all possible.  This just involves looking up the $wl
+values for system compilers.
+
+* What should be done about the difference between -fpic and -fPIC?
+
+* GCC docs imply that all rs6000 code is PIC.  If that is true, then
+implement it.
