Unresolved dlopen issues
========================

   The following problems are not solved by using libtool's dlopen
support:

   * Dlopen functions are generally only available on shared library
     platforms.  If you want your package to be portable to static
     platforms, you have to use either libltdl (Note: Using libltdl)
     or develop your own alternatives to dlopening dynamic code.  Most
     reasonable solutions involve writing wrapper functions for the
     `dlopen' family, which do package-specific tricks when dlopening
     is unsupported or not available on a given platform.

   * There are major differences in implementations of the `dlopen'
     family of functions.  Some platforms do not even use the same
     function names (notably HP-UX, with its `shl_load' family).

   * The application developer must write a custom search function in
     order to discover the correct module filename to supply to
     `dlopen'.
