ffindex_apply_mpi: - apply a program to each FFindex entry (mpi enhanced)

       User  feedback  is welcome, especially bugs, performance issues and last but not least convenience of the
       programs and API.

ffindex_apply_mpi: invalid option -- 'v'          November 2024                            FFINDEX_APPLY_MPI:(1)

       -l     LOG_FILE  like  an  FFindex  file  but  with  the  return  value of apply added.  This file can be
              processed  and  used  as  FFindex  file.   E.g.  grep  "      1$"  foo.log  |   cut   -f   1-3   >
              foo-special.ffindex.    where   maybe  the  ffindex_apply_mpi  ran  with  --  perl  -e  'return  1
              if(/^SPECIAL/)'

       -m     Do not merge the FFindex parts generated by the different MPI processes This is useful  for  large
              MPI Jobs where merge time might be accounted.

       -d     FFDATA output file, stdout of program will be captured

       -i     FFINDEX output file, entries get the same name as input entry
