"""
Welcom 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 ocaml_global

By default all the option are executed.

Options:
    -h --help
    --irpf90           Create the `ezfio_interface.irpf90`
                             which contains all the providers needed
                             (aka all with the `interface: input` parameter)
                             in `${pwd}`
    --ezfio_config     Create the `${module_lower}_ezfio_interface_config` in
                             `${QPACKAGE_ROOT}/EZFIO/config/`
                       This file is needed by *EZFIO* to create the `libezfio.so`
    --ocaml            Create the `Input_module.lower.ml` for the *qp_edit*
    --ezfio_default    Create the `${module_lower}_ezfio_interface_default` in
                             `${QPACKAGE_ROOT}/data/ezfio_defaults` needed by
                             the ocaml
    ocaml_global       Create the qp_edit

Format specification :
    [provider_name]  | the name of the provider in irp.f90
    doc:{str}        | Is the doc
    Type:{str}       | Is a fancy_type supported by the ocaml
    ezfio_name:{str} | Will be the name of the file for the ezfio
                       (optional by default is the name of the provider)
    interface:{str}  | The provider is a imput or a output
    default:{str}    | The default value if interface == input:
    size:{str}       | the size information
                        (like 1 or =sum(ao_num) or (ao_num,3) )

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

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