"""Minimal script for geostationary production.
We take the case of HRIT data from meteosat 9, as send through eumetcast.
- Install mipp, mpop, and pyresample
- Don't forget to set up the PPP_CONFIG_DIR variable to point to your
configuration files.
- Edit the meteosat09.cfg configuration file (a template is provided in case
you don't have one) with your HRIT directory:
.. code-block:: ini
[seviri-level1]
format = 'xrit/MSG'
dir='/data/hrit_in'
filename='H-000-MSG?__-MSG?________-%(channel)s-%(segment)s-%Y%m%d%H%M-__'
filename_pro='H-000-MSG?__-MSG?________-_________-%(segment)s-%Y%m%d%H%M-__'
filename_epi='H-000-MSG?__-MSG?________-_________-%(segment)s-%Y%m%d%H%M-__'
where `/data/hrit_in` has to be changed to anything that suits your
environment.
- Here is an example of a minimal script that has to be called as soon as an
MSG slot has arrived (usually, watching the arrival of the epilogue file
suffices)
