Contributions are regrouped in various sections that will change with the available material. This fractionning is mainly intended to make easier the access to the required resource. Practicallity more than theoretical considerations is at the basis of this organization.

There will be always a "varia" section that will contain all the resources that have not yet been assigned to a precise section of some import; most of the time, such resources will have little relationship between them.

The necessary code for the functions or subs of a section can be downloaded as a "section" zip file.
