Please read the following if you are about to use AbiPy for the first time:

Abipy needs to know about the cluster/computer you are running on. This information
is provided via the manager.yml and scheduler.yml files.
These files must be located in ~/.abinit/abipy or in the working directory in which you execute the flow.
Examples are provided in abipy/data/managers.
See also the HTML page:

    http://abinit.github.io/abipy/workflows/manager_examples.html

TIP: Use abicheck.py to validate the final configuration.

Have fun!
