'''Service for accessing a jail's filesystem.
This application is a wrapper around the library module fileservice, running
it through trampoline.
It receives file handling instructions as requests, performs actions on the
student's workspace, and returns directory listings in JSON.
See the documentation in ivle.fileservice_lib for details.
