:mod:`plainbox.impl.secure.providers` -- providers package
==========================================================

Providers are a mechanism by which PlainBox can enumerate jobs and test plans.
Currently there are only v1 (as in version one) providers that basically have
to behave as CheckBox itself (mini CheckBox forks for example)

V1 providers
------------

The first (current) version of PlainBox providers has the following properties,
this is also described by :class:`plainbox.abc.IProvider1`::

    * there is a directory with '.txt' or '.txt.in' files with RFC822-encoded
      job definitions. The definitions need a particular set of keys to work.

    * there is a directory with additional executables (added to PATH)

    * there is a directory with an additional python3 libraries (added to
      PYTHONPATH)
