#/*
# enum_quda_fortran.h
#
#   This  is  Fortran  version  of  enum_quda.h.   This  is  currently
#   generated by hand,  and so must be matched  against an appropriate
#   version  of QUDA.   It would  be nice  to auto-generate  this from
#   enum_quda.h and this should probably use Fortran enumerate types 
#   instead (this requires Fortran 2003, but this is covered by 
#   gfortran).
