!
! NJOY is a system of processing modules intended to convert evaluated
! nuclear data in the ENDF format into forms useful for practical
! applications.  It consists of a number of independent processing
! modules that perform various processing tasks and this main program
! (njoy) that runs the modules in the desired order.  The modules
! currently available are the following:
!
! reconr...reconstruct pointwise cross sections from ENDF/B resonance
!          parameters and interpolation schemes.
!
! broadr...doppler broaden and thin pointwise cross sections.
!
! unresr...compute effective pointwise self-shielded cross sections in
!          the unresolved energy range.
!
! heatr....compute heat production cross sections (kerma) and damage
!          energy production.
!
! thermr...generate neutron scattering cross sections and
!          point-to-point scattering kernels in the thermal range for
!          free or bound atoms.
!
! groupr...generate self-shielded multigroup cross sections and
!          group-to-group scattering and photon production matrices.
!
! gaminr...compute multigroup photon interaction cross sections,
!          scattering matrices, and heat production.
!
! errorr...construct multigroup covariance matrices.
!
! covr.....process covariance data from errorr.
!
! moder....convert between ENDF/B standard coded mode and the njoy
!          blocked binary mode.
!
! dtfr.....output and plot multigroup data for discrete ordinates
!          transport codes.
!
! ccccr....format multigroup data into the CCCC standard interface
!          files ISOTXS, BRKOXS, and DLAYXS.
!
! matxsr...convert multigroup data into the comprehensive MATXS
