SUBROUTINE DUO006(IPLIB,IPRINT,NISOT,NGRP,HREAC,IDIV,RHS,
> FLUX,AFLUX)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Processing one of the two microlibs and return the RHS matrix for
* the single reaction HREAC.

*Author(s): A. Hebert
*
*Parameters: input
* IPLIB microlib.
* IPRINT print parameter.
* NISOT number of isotopes.
* NGRP number of energy groups.
* HREAC character*8 reaction name of the reaction to process.
* IDIV type of divergence term processing (=0: no processing;
* =1: direct processing; =2: adjoint processing;
* =3: direct-adjoint processing).
*
*Parameters: output
* RHS macroscopic cross-section matrix.
* FLUX integrated direct flux.
* AFLUX integrated adjoint flux.
