(Most of) the file names of the CO5BOLD tar ball are shown in Tables 3.2 and 3.3. Available tweak and scaling files are listed in Tab. 3.4. The - few - corresponding unit-test files are listed in Tab. 3.5.
Program-file names are short, without hyphen (rhd.F90, rhdmpi.F90, rhdut.F90).
However, to avoid name-space pollution,
very short names for subroutines, functions, modules and their corresponding files
are strongly discouraged.
Instead, one level of grouping as, e.g.,
subroutine timing_start and subroutine timing_stop in timing_module,
or two levels as, e.g.,
subroutine rhd_hyd_Step in rhd_hyd_module,
are recommended.
In these cases, the files are named as the modules they contain, i.e.,
timing_module.F90
and
rhd_hyd_module.F90,
respectively.
As Fortran free format is preferred, the normal file suffix is .f90
(or .F90 for files that have to be processed with a preprocessor during
the compiling step),
even if language elements beyond Fortran90 are used.
