1. Introduction

It was explained in [D1.01.01] how a developer could « overload » Code_Aster with personal sources. The sources we are talking about here are:

• FORTRAN, or C routines

• Python sources

• catalogs,

• test cases.

A classic development of Aster generally results in:

• the modification of certain sources,

• the writing of new sources.

The modification of sources requires their prior extraction (copying) from the official sources. Paragraph § 2 ../wiki/doku.php%3FID=en:P03_Dev:D02:D02:D20101_Regles_Extrac_Restit_Src%23Regles_d_Extraction is about extraction rules.

Once the development is complete, it can be « restored »: the official sources are then updated. Paragraph § 3 ../wiki/doku.php%3FID=en:P03_Dev:D02:D02:D20101_Regles_Extrac_Restit_Src%23Regles_de_Restition concerns the return rules.
