We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Hydra client API
Create Hydra client API to allow jobs to interact with Hydra.
one immediate need is to allow executed code to find out what is the original working directory is was executed from.

--- END ISSUE ---

Below are some code segments, each from a relevant file. One or more of these files may contain bugs.
