== Mandatory switches ==
Of each of the below groups of switches exactly one has to be selected.

----
The first group of switches controls the selection of machine-dependent code.
<br />
''f90''   &emsp; FORTRAN-90 style date and time capturing and program
abort.
<br />
''dum''  &emsp; Dummy to be used if WAVEWATCH III is to be installed
on previously untried hardware.

----
Hardware model (first group) and message passing protocol (second group).
<br />
''shrd'' &emsp; Shared memory model.
<br />
''dist'' &emsp; Distributed memory model.

''shrd''  &emsp; Shared memory model, no message passing.
<br />
''mpi''  &emsp; Message Passing Interface (MPI).

----
Word length used to determine record length in direct access files
<br />
''lrb4''  &emsp; 4 byte words.
<br />
''lrb8''  &emsp; 8 byte words.

----
Compilation as a subroutine (called by a coupled model system using PALM)
or a stand-alone program.
<br />
''nopa''  &emsp;  Compilation as a stand-alone program.
<br />
''palm''  &emsp;  Compilation as a subroutine.

----
Selection of propagation schemes and GSE alleviation method. 
<br />
These represent two sets of switched with some shared switches between the groups.
<br />
Note that the second set of switches is secondary to the selection of program modules in the first set of switches, and therefore, does not have a user-defined option.
<br />
''pr0'' &emsp;  No propagation scheme / GSE alleviation used.
<br />
''pr1'' &emsp;  First order propagation scheme, no GSE alleviation.
<br />
''pr2'' &emsp;  Higher order schemes with Booij and Holthuijsen (1987) dispersion correction.
<br />
''pr3'' &emsp;  Higher order schemes with Tolman (2002a) averaging technique.
<br />
''prx'' &emsp;  Experimental (user supplied).

''pr0'' &emsp; No propagation scheme used.
<br />
''pr1'' &emsp; First order propagation scheme.
<br />
''uno'' &emsp; Second order (UNO) propagation scheme.
<br />
''uq''  &emsp; Third order (UQ) propagation scheme.

----
Selection of flux computation:
<br />
''flx0'' &emsp;  No routine used; flux computation included in source terms,
<br />
''flx1'' &emsp;  Friction velocity according to Eq. (2.47).
<br />
''flx2'' &emsp;  Friction velocity from Tolman and Chalikov input.
<br />
''flx3'' &emsp;  Idem, with cap of Eq. (2.69) or (2.70).
<br />
''flx4'' &emsp;  Friction velocity according to Eq. (2.127).
<br />
''flxx'' &emsp;  Experimental (user supplied).

----
Selection of linear input:
<br />
''ln0''  &emsp;  No linear input.
<br />
''seed''  &emsp; Spectral seeding of Eq. (3.70).
<br />
''ln1''  &emsp;  Cavaleri and Malanotte-Rizzoli with filter.
<br />
''lnx''  &emsp;  Experimental (user supplied).

----
Selection of input and dissipation. stabn switches are optional and additional to corresponding stn switch:
<br />
''st0''  &emsp;   No input and dissipation used.
<br />
''st1''  &emsp;   WAM3 source term package.
<br />
''st2''  &emsp;   Tolman and Chalikov (1996) source term package. See also the optional stab2 switch.
<br />
''stab2'' &emsp;  Enable stability correction (2.86) - (2.89) for st2.
<br />
''st3''  &emsp;   WAM4 and variants source term package.
<br />
''stab3'' &emsp;  Enable stability correction from Abdalla and Bidlot (2002) for st4.
<br />
''st4''  &emsp;   Ardhuin et al. (2010) source term package.
<br />
''st6''  &emsp;   BYDRZ source term package.
<br />
''stx''  &emsp;   Experimental (user supplied).
