# This module can read data from a python file in the source folder. This will read data from the version being built (as opposed to standard sphinx-multiversion behavior that executes python from the working copy)
# All global variables defined in file current_version_data.py will be put in html_context['current_version_data'] which allows to use them in HTML templates.
