Start documentation

Use sphinx with astropy _templates (it would be great to make pcigale an
affilated package).
Make the skeleton of the documentation.
Start to write pcigale script usage.

+How to use pcigale script
+#########################
+
+pcigale comes with a script (a programme callable from the command line) that
+will help you to run the complete analysis of a set of galaxy with known
+redshift and fluxes in various filters.
+
+Generation of a minimal configuration files
+===========================================
+
+First, you need a minimal configuration file. Create a directory where you
+will proceed with your analysis. In a shell, go inside this directory and
+launch ``pcigale init``. This will create a *pcigale.ini* file in the
+directory with that content:
+
+.. code-block:: cfg
+  :emphasize-lines: 4,9,14,17
+
+  # File containing the observation data to be fitted. Each flux column
+  # must have the name of the corresponding filter, the error columns are
+  # suffixed with '_err'. The values must be in mJy.
+  data_file =
+
+  # Order of the modules use for SED creation. Available modules : bc03,
+  # dh2002, dl2007, dustatt_calzleit, dustatt_powerlaw, igmattenuation,
+  # lines, loadfile, m2005, sfh2exp, sfhfromfile.
+  sed_modules = ,
+
+  # Module used to redshift the SED before the integration in the filters.
+  # This is a SED creation module that accepts a 'redshift' parameter (see
+  # the documentation).
+  redshift_module =

+You need to edit this file to complete:
+
+* *data_file* is the name of the file containing you observations. This is a
+  FITS or VO-Table file containing the observations to be analysed. It must
+  contain a column named *id* with an identifier for each source, a column
+  named *redshift* and columns containing the fluxes in *mJy* in various
+  filters. The flux columns must be named exactly as the corresponding filters
+  in the pcigale database. When a column is the error associated with a
+  filter, its name must prefix the filter name with *_err*.
+
+* *sed_modules* is the list of pcigale SED creation modules, **in the right
+  order**, that will be used to create the theoretical SED (see the various
+  module documentations). The comments above the entry list the available
+  modules.
+
+* *redshift_module* is the name of the module that will be used to redshift
+  and add IGM attenuation to the SED before computing the fluxes that will be
+  compared to observed ones.
+
+* *analysis_method* is the name of the statistical analysis module that will
+  be used. Here again, the comments list the available modules.
+
+Here is a sample completed minimal configuration file:
+
+.. code-block:: cfg
+
+  # File containing the observation data to be fitted. Each flux column
+  # must have the name of the corresponding filter, the error columns are
+  # suffixed with '_err'. The values must be in mJy.
+  data_file = data.fits
+
+  # Order of the modules use for SED creation. Available modules : bc03,
+  # dh2002, dl2007, dustatt_calzleit, dustatt_powerlaw, igmattenuation,
+  # lines, loadfile, m2005, sfh2exp, sfhfromfile.
+  sed_modules = sfh2exp, m2005, dustatt_calzleit, dh2002
+
+  # Module used to redshift the SED before the integration in the filters.
+  # This is a SED creation module that accepts a 'redshift' parameter (see
+  # the documentation).
+  redshift_module = igmattenuation
+
+  # Method used for statistical analysis. Available methods: psum.
+  analysis_method = psum
+
+Generation of the main configuration file
+=========================================
+
+You can now run the ``pcigale genconf`` command. pcigale will read the data
+file to identify which columns contain filter fluxes and errors. It will then
+pick each module and add their configuration section to the ini file, that
+will become something like this:
+
+.. code-block:: cfg
+
+   # File containing the observation data to be fitted. Each flux column
+   # must have the name of the corresponding filter, the error columns are
+   # suffixed with '_err'. The values must be in mJy.
+   data_file = data.fits
+
+   # Order of the modules use for SED creation. Available modules : bc03,
+   # dh2002, dl2007, dustatt_calzleit, dustatt_powerlaw, igmattenuation,
+   # lines, loadfile, m2005, sfh2exp, sfhfromfile.
+   sed_modules = sfh2exp, m2005, dustatt_calzleit, dh2002
+
+   # Module used to redshift the SED before the integration in the filters.
+   # This is a SED creation module that accepts a 'redshift' parameter (see
+   # the documentation).
+   redshift_module = igmattenuation
