/****** spool/spool_create_dynamic_context() *********************
*  NAME
*     spool_create_dynamic_context() -- create a spooling context
*
*  SYNOPSIS
*     lListElem * 
*     spool_create_dynamic_context(lList **answer_list, 
*                                  const char *shlib_name, const char *args) 
*
*  FUNCTION
*     Create a spooling context.
*     Which spooling context to use can either be defined at compile time, e.g. 
*     by calling "aimk -spool-classic" or "aimk -spool-flatfile".
*
*     Or dynamic loading of a spooling framework is activated (by building
*     with "aimk -spool-dynamic".
*     In this case a shared library is dynamically loaded and the spooling
*     framework implementation of that shared library is used.
*
*  INPUTS
*     lList **answer_list    - to return error messages
*     const char *shlib_name - name of a shared lib
*     const char *args       - arguments to be passed to the initialization
*                              function in the specified shared lib.
*
*  RESULT
*     lListElem * - on success a spooling context, else NULL.
*
*  SEE ALSO
*     spool/--Spooling
