How does it work ?
===================
Operational chains are in Python. All treatments are launched on batch, on Caparmor.

* Configuration file (see section before): this is the only file you will have to modify, it contains all the treatments.

* To have the treatments list:

  * For MANGAE : **launch_mangae config_mangae.cfg --list**
  * For MENOR : **launch_menor config_menor.cfg --list**

* To launch all available treaments:

::

    launch_mangae config_mangae.cfg (for MANGAE)
    launch_menor config_menor.cfg (for MENOR)


* To launch only some treatments:

::

  launch_mangae config_mangae.cfg --only meteo
  launch_mangae config_mangae.cfg --only meteo,river

* To launch all treatments, except one ore more:

::

  launch_mangae config_mangae.cfg --no meteo
  launch_mangae config_mangae.cfg --no meteo,river


* To run operational chain from 01/01/2014 (date start) to 05/01/2014 (date end):

::

    launch_mangae config_mangae.cfg -s 2014-01-01,00:00 -e 2014-01-05,00:00

If no start and end date are specified, the start date is **default** specified in section **restart**, and the end date is **forecast_range** specified in section **run**. In this example,run will be from J-1 to J+4 (J is the current day):

::

 [restart]
   default = 'J-1,00h'

::

 [run]
  forecast_range = 'J+4,00h'

* To kill a job, use option **--kill** (soft way using *qdel*) or **--slay** (hard way using *qdel -W force*) 

::

 launch_mangae config_mangae.cfg --slay meteo
 launch_mangae config_mangae.cfg --slay all

 
* To follow runs, check the file **f1-mangae.xml** or **f2-menor.xml** which will be created each time you run the chain. It contains warnings and errors, and will specify if treatments are OK or KO.

* logs files are in **./logs**
