Implementation of the code

Embedded documentation

ORCHIDEE has a scientific documentation embedded into the code that generates html and pdf versions.

See ORCHIDEE_DOC page for knowing more about this documentation.

Coding Guidelines

Coding guidelines have been established to facilitate the development of the ORCHIDEE code. All developers should follow thes guide lines when improving or adding new features to the code. Moreover, any new suggestions to these coding guide lines, in order to improve the readability, the efficiency and the robustness of the code are welcome. You can make these suggestions to the ORCHIDEE project group. See coding_guidelines.pdf and coding_guidelines.doc
