    Each session has a small amount of meta-data that is available for
    inspection. Each session has an application identifier (set by the
    application that created that session), a title, that is human readable
    piece of text that helps to distinguish sessions, and a set of flags.

    Flags are particularly useful for determining what is the overall state
    of any particular session. Two flags are standardized (other flags can be
    used by applications): incomplete and submitted. The 'incomplete' flag is
    removed after all desired jobs have been executed. The 'submitted' flag
    is set after a submission is made using any of the transport mechanisms.

    General purpose of this command is to make development of qml-native jobs
    faster, by making it easier to test qml file(s) that constitute to job
    without resorting to installation of provider and running plainbox run.
    Typical approach to the development of new qml job would be as follows:

    - have an idea for a job

    - create a qml file in Ubuntu-SDK or Your Favourite Editor

    - hack on the file and iterate using qmlscene (or use plainbox-qml-shell
      immediately if you start with next point)

    - make it conformant to plainbox qml-native API described in CEP-5
      (calling test-done at the end)

    - copy qml file over to data dir of a provider and add a job unit to it

    install this provider in the system

    This command installs the provider to the specified prefix.

    Installation Layouts
    ====================

    There are two possible installation layouts: flat, perfect for keeping the
    whole provider in one directory, and unix, which is optimized for
    packaging and respecting the filesystem hierarchy.

    In both cases, a generated file is created at a fixed location:

        {prefix}/share/plainbox-providers-1/{provider.name}.provider

    This file is essential for plainbox to discover providers. It contains
    meta-data collected from the manage.py setup() call.

    For Packaging
    -------------

    System-wide installations should typically use `--prefix=/usr` coupled
    with `--layout=unix`. For packaging you will want to use the `--root=`
    argument to place all of the copied and generated files into your packaging
    system staging area. This will not affect generated content, which only
    respects the prefix argument.

    UNIX Layout
    -----------

    In the unix layout, following transformation is applied:

    @LAYOUT[unix]@

    Flat Layout
    -----------

    @LAYOUT[flat]@
