C     *==========================================================*
C     | PTRACERS_START.h
C     | o Holds passive-tracer internal parameters related

C     *==========================================================*
C     | Passive-tracer internal parameters/variables related to
C     | a) which tracer is stepped forward
C     | b) writing or reading pickup for a restart.
C     | Note:
C     |  external parameters (read from parameter file "data.ptracers")
C     |  stay in PTRACERS_PARAMS.h and should not appear here ;
C     |  therefore, this header file should not be included
C     |  in S/R PTRACERS_READPARMS.
