tests before being passed to @file{config.status} for inclusion in the
generated libtool script.
+@defmac LT_OUTPUT
+By default, the configured @file{libtool} script is generated by the
+call to @code{AC_OUTPUT} command, and there is rarely any need to use
+@file{libtool} from @file{configure}. However, sometimes it is
+necessary to run configure time compile and link tests using
+@file{libtool}. You can add @code{LT_OUTPUT} to your
+@file{configure.ac} any time after @code{LT_INIT} and any
+@code{LT_LANG} calls; that done, @file{libtool} will be created by a
+specially generated @file{config.lt} file, and available for use in
+later tests.
+
+Also, when @code{LT_OUTPUT} is used, for backwards compatibility with
+Automake regeneration rules, @file{config.status} will call
+@file{config.lt} to regenerate @file{libtool}, rather than generating
+the file itself.
+@end defmac

When you invoke the @command{libtoolize} program (@pxref{Invoking
libtoolize}), it will tell you where to find a definition of
