-"""Javelin is a tool for creating, verifying, and deleting a small set of
-resources in a declarative way.
-
-Javelin is meant to be used as a way to validate quickly that resources can
-survive an upgrade process.
-
-Authentication
---------------
-
-Javelin will be creating (and removing) users and tenants so it needs the admin
-credentials of your cloud to operate properly. The corresponding info can be
-given the usual way, either through CLI options or environment variables.
-
-You're probably familiar with these, but just in case::
-
-    +----------+------------------+----------------------+
-    | Param    | CLI              | Environment Variable |
-    +----------+------------------+----------------------+
-    | Username | --os-username    | OS_USERNAME          |
-    | Password | --os-password    | OS_PASSWORD          |
-    | Tenant   | --os-tenant-name | OS_TENANT_NAME       |
-    +----------+------------------+----------------------+
-
-
-Runtime Arguments
------------------
-
-**-m/--mode**: (Required) Has to be one of 'check', 'create' or 'destroy'. It
-indicates which actions javelin is going to perform.
-
-**-r/--resources**: (Required) The path to a YAML file describing the resources
-used by Javelin.
-
-**-d/--devstack-base**: (Required) The path to the devstack repo used to
-retrieve artefacts (like images) that will be referenced in the resource files.
-
-**-c/--config-file**: (Optional) The path to a valid Tempest config file
-describing your cloud. Javelin may use this to determine if certain services
-are enabled and modify its behavior accordingly.
-
-
-Resource file
--------------
-
-The resource file is a valid YAML file describing the resources that will be
-created, checked and destroyed by javelin. Here's a canonical example of a
-resource file::
-
-  tenants:
-    - javelin
-    - discuss

-An important piece of the resource definition is the *owner* field, which is
-the user (that we've created) that is the owner of that resource. All
-operations on that resource will happen as that regular user to ensure that
-admin level access does not mask issues.
-
-The check phase will act like a unit test, using well known assert methods to
-verify that the correct resources exist.

 Usage
 -----
 
-subunit-describe-calls will take in a file path via the --subunit parameter
-which contains either a subunit v1 or v2 stream. This is then parsed checking
-for details contained in the file_bytes of the --non-subunit-name parameter
-(the default is pythonlogging which is what Tempest uses to store logs). By
-default the OpenStack Kilo release port defaults (http://bit.ly/22jpF5P)
-are used unless a file is provided via the --ports option. The resulting output
-is dumped in JSON output to the path provided in the --output-file option.
