### PyGildas modules

Most of the Gildas packages can be directly imported as Python modules:

- import pysic
- import pygreg
- import pyastro
- import pyclass6
- import pyclic
- import pymapping

During the import, 3 steps are executed:

- SIC (resp. GreG) is initialized as a background process,
- the Sic object is instantiated into Python __main__ (see subsection ),
- all SIC variables are imported into Python __main__ (see subsection ).

From this point, you can use the (shared) variables, jump to SIC prompt, and use any of the methods the module defines (see hereafter).
