optionFileLoad - Load the locatable config files, in order


   #include <your-opts.h>
   cc [...] -o outfile infile.c -lopts [...]

   int optionFileLoad(tOptions * opts, char const * prog);


   This   function   looks   in   all  the  specified  directories  for  a
   configuration file ("rc" file or "ini" file) and  processes  any  found
   twice.   The  first  time  through, they are processed in reverse order
   (last file first).  At that time, only "immediate action" configurables
   are  processed.   For  example,  if  the  last named file specifies not
   processing any more configuration files,  then  no  more  configuration
   files  will  be processed.  Such an option in the first named directory
   will have no effect.

   Once the immediate action configurables have  been  handled,  then  the
   directories  are  handled in normal, forward order.  In that way, later
   config files can override the settings of earlier config files.

   See the AutoOpts documentation for a thorough discussion of the  config
   file format.

   Configuration files not found or not decipherable are simply ignored.

   opts   program options descriptor

   prog   program name


   0 -> SUCCESS, -1 -> FAILURE


   Returns  the  value,  "-1"  if the program options descriptor is out of
   date or indecipherable.   Otherwise,  the  value  "0"  will  always  be
