"""
Welcome to the ei_handler.
We will create all the ezfio related stuff from a EZFIO.cfg file.

Usage:
    ei_handler.py [--path_module=<module>]
                  [--irpf90]
                  [--ezfio_config]
                  [--ocaml]
                  [--ezfio_default]
    ei_handler.py list_supported_types
    ei_handler.py ocaml_global

By default all the option are executed.

Options:
    -h --help
    --irpf90        Create the `<module>/ezfio_interface.irpf90`
                         which contains all the providers needed
    --ezfio_config  Create the `<module_lower>_ezfio_interface_config` in
                          `${QP_EZFIO}/config/`
    --ocaml         Create all the stuff needed by *qp_edit*:
                             -`Input_<module_lower>.ml` and
                             - <module_lower>_ezfio_interface_default`
    ocaml_global    Create the *qp_edit*

Format specification :

Required:
    [<provider_name>]   The name of the provider in irp.f90 and in the EZFIO lib
    doc:<str>           The plain text documentation
    type:<str>          A Fancy_type supported by the ocaml.
                            type `ei_handler.py get_supported_type` for a list
    interface:<str>     The interface is list of string sepeared by ","  which can contain :
                          - ezfio (if you only whant the ezfiolib)
                          - provider (if you want the provider)
                          - ocaml (if you want the ocaml gestion)
Optional:
    default: <str>      The default value needed,
                            if 'ocaml' is in interface list.
                           ! No list is allowed for now !
    size: <str>         The size information.
                            (by default is one)
                            Example : 1, =sum(ao_num); (ao_num,3)
                            ATTENTION : The module and the value are separed by a "." not a "_".
                            For example (determinants.n_det)
    ezfio_name: <str>   The name for the EZFIO lib
                             (by default is <provider_name>)
    ezfio_dir: <str>    Will be the folder of EZFIO.
                              (by default is <module_lower>)

Example of EZFIO.cfg:
```
[thresh_SCF]
doc: Threshold on the convergence of the Hartree Fock energy
type: Threshold
default: 1.e-10
interface: provider,ezfio,ocaml
size: 1

[energy]
type: double precision
doc: Calculated HF energy
interface: ezfio
```
