+### Command line
+
+The **init.sh** script allows some command line parameters and some environement
+variables to change it's behaviour.
+
+The parameters are:
+
+- **-m \<list\>, --module=\<list\>**: Allows to manually give a module list and
+overide the *MODULE_LIST* variable declaration. The list is a comma separated
+module name. If that option is provided, the module list is mandatory.
+- **-c, --check-only**: Do not launch any actions, only the checks are launched.
+In that situation, no change should be done to the system.
+- **-j, --jump**: Jump the checks and goes directly to system transformation.
+That option should only be run after successfull checks (eg. after using the
+**--checkonly** option).
+- **-k, --keep-going**: The scripts will continue even if errors occurs. Thus
+some unrecoverable errors might stop the script anyway if it not allowing it to
+work.
