-======================
-Programming guidelines
-======================
-
-Each module (directory) contains the following:
-
-* A ``README.rst`` file to document the current module.
-* An ``ASSUMPTIONS.rst`` file. This file should document all the implicit
-  assumptions used in the module. For example, if the atomic orbitals are
-  assumed to be normalized, this should be mentioned in the
-  ``AOs/ASSUMPTIONS.rst`` file.
-* A ``NEEDED_MODULES`` file which contains the list of modules on which the
-  current module depends
-* A set of ``.irp.f`` files containing provider, subroutines and functions
-* A ``Makefile`` that should compile
-* Optionally some ``*.ezfio_config`` configuration files for the EZFIO
-  library
-
-A new module may be created by invoking the ``create_module.sh`` script.
-
-Every subroutine, function or provider should be documented using the
-BEGIN_DOC ... END_DOC block. The documentation should be written in
-ReStructured Text format to enable the automatic generation of the Sphinx
-documentation.
-
-When the current module depends on other modules, the list of modules should
-be added in the ``NEEDED_MODULES`` file.
-
-
-Creating a new module
-=====================
-
-Every new module should be created using the interactive ``create_module.sh``
-script located in the ``${QP_ROOT}/scripts`` directory. This will create
-all the required files with correct templates.
-
-
-Makefiles
-=========
-
-Use the structure of Makefiles provided by the ``create_module.sh`` script. If
-you need to re-create the Makefile, you can use the ``create_Makefile.sh``
-script in the current module directory.
-
-If you need to add some Fortran or C files that should not be tracked by IRPF90,
-you have to add them manually to the Makefile in the ``SRC`` variable.
-You also need to add the corresponding ``*.o`` file prefixed by ``IRPF90_temp/``.
-For example
-
-.. code-block:: Makefile
-
-  SRC=map_module.f90
-  OBJ=IRPF90_temp/map_module.o
-
-
-
-Input data
-==========
-
-Every program is supposed to use an EZFIO database containing all the
-persistent data. This database can be modified in using the generated Fortran
-functions or the generated Python module.
-
-The definition of the data needed by the module should be put in the
-``*.ezfio_config`` file.
-
-Input data can also be read from the standard input to enable the use of
-a program with a pipe, but the read statements should be present **only** in
-the main program.
-
-
-Output data
-===========
-
-Print to stdout statements should only appear in programs, not in providers,
-subroutines or functions. This enables the possibility easily use the programs
-with pipes.
-
-To print, you should write in an output file provided by the ``Output``
-module. Every module has its own output file. Before printing something,
-a timestamp should be put in the output with the ``write_time`` function.
-This allows an external script to read all the pieces of the output files
-and put them in a sequential order. The format of the output should be
-in ReStructured Text for easy transformation of the output data to pdf,
-HTML, man, etc.
-
-
-Creating a shell script
-=======================
-
-Shell scripts should be located in the ``${QP_ROOT}/scripts`` directory.
-Relative paths should be avoided as much as possible, and the result of commands
-should be always checked. For example, when creating a directory the existence
-of the directory has to be checked.
