Typical tasks for the developer in the recipe system are:
Specifying recipe definitions:Here, which variables describe the recipe are specified. In
order to prevent any misunderstanding, please note that this does not concern the values
of variables. These are not specified until the runtime.
Adapting designs, editing recipe values: In principle, the existing command elements that
are tied to the variables in the process can be used.
Adapting designs, managing recipe files: Typical tasks such as loading or saving recipe
values from files usually require a list of the existing recipe files.
