"""Command line tool to handle Postgresql WAL archiving on Rackspace's cloudfiles.
``pg_raxarchive`` is a command line tool to handle Postgresql WAL archiving on
Rackspace's cloudfiles.
Quick help
Install using pip then:
- Create a file ``/etc/pg_raxarchive.ini`` with rackspace credentials (see below).
- Run ``pg_raxarchive upload {path_to_file} {basename}`` to upload archive a file.
- Run ``pg_raxarchive download {basename} {path_to_file}`` to download an archived file.
- Run ``pg_raxarchive cleanup {filename}`` to remove WAL files older than {filename}.
Rackspace credential file follows pyrax format::
    username = YUOR_USERNAME_HERE
    api_key  = YOUR_API_KEY_HERE
You can customize the region and the container name using:
- ``pg_raxarchive --container CONTAINE_RNAME ...``
- ``pg_raxarchive --region REGION_NAME ...``
By default ``pg_raxarchive`` expects to be running inside rackspace network. If this is
not your case or you want to be billed for some other reasons use ``pg_raxarchive --use-public``.
* Run ``pg_raxarchive --help`` to know more.
