Additional rules
======================


Fortran modules
---------------

During compilation, it is necessary to compile the modules in the order imposed by their inter-dependencies, and then, to compile the routines that use these modules.

To quickly and automatically identify the modules, the following naming is therefore imposed:


* xxxx_type.F90 for modules that define derived types (one type per module) and basic methods for creating objects of this type;


* xxxx_module.F90 for "methods" on types.

All derived types should be documented (as are Jeveux data structures).


Constants
----------

The abundant use of #define is avoided.

Instead, it is necessary to define parameters grouped thematically in a module.
