! HotConcat
! Author: Ben Payment 07.17.2006
!
! Program take hotfiles created from SWAN parallel runs and compiles them
! into a single file.
!
! Read command line arguments (only in case of Fortran 2003)
! HotConcat [-v] [-s] [-h halosize] <basefile>
! <basefile> refers to the base file name used for hotfiles
! [-v] verbose mode: program reports non-error information
! [-h halosize] optional argument which changes the overlap halo from default value
! [-s] stomp over existing basefile
! [help] [-help] display above information
!
! In case of non-Fortran 2003, read arguments via arg_nml namelist from
! hcat.nml file.
