"""create_application(name=None, blueprint=None, vms=None, cloud=None, \
region=None, wait=True, show_progress=True)
Create a new application.
If *blueprint* is specified, then it must be the name of a blueprint from
which the application is created. If *blueprint* is not specified, then an
application will be created from scratch in which case *vms* needs to be
specified containing a list of the VM definitions. The VM definitions are
dictionaries containing string keys describing the VM. The arguments
*cloud* and *region* specify which cloud and region to publish the
application to. If these are not specified, the application is published
to the lowest cost cloud that fits the VM definitions. If *wait* is
nonzero, then this function will wait until the application is started up
and its VMs are accessible via ssh. If *show_progress* is nonzero, then a
progress bar is shown.
The return value of this function is the application definition of the
application that was created. In case of an error, an exception is raised.
.. seealso::
See :ref:`vm-ref` for the possible keys in a VM definition dictionary.
