Using libltdl
*************

   Libtool provides a small library, called `libltdl', that aims at
hiding the various difficulties of dlopening libraries from programmers.
It consists of a header-file and a small C source file that can be
distributed with applications that need dlopening functionality.  On
some platforms, whose dynamic linkers are too limited for a simple
implementation of `libltdl' services, it requires GNU DLD, or it will
only emulate dynamic linking with libtool's dlpreopening mechanism.

libltdl supports currently the following dynamic linking mechanisms:

   * `dlopen' (Solaris, Linux and various BSD flavors)

   * `shl_load' (HP-UX)

   * `LoadLibrary' (Win16 and Win32)

   * `load_add_on' (BeOS)

   * GNU DLD (emulates dynamic linking for static libraries)

   * libtool's dlpreopen (see Note: Dlpreopening)

License, with the following exception:

     As a special exception to the GNU Lesser General Public License,
     if you distribute this file as part of a program or library that
     is built using GNU libtool, you may include it under the same
