# This is an EDMC 'core' plugin.
#
# All EDMC plugins are *dynamically* loaded at run-time.
#
# We build for Windows using `py2exe`.
#
# `py2exe` can't possibly know about anything in the dynamically loaded
# core plugins.
#
# Thus you **MUST** check if any imports you add in this file are only
# referenced in this file (or only in any other core plugin), and if so...
#
#     YOU MUST ENSURE THAT PERTINENT ADJUSTMENTS ARE MADE IN `setup.py`
#     SO AS TO ENSURE THE FILES ARE ACTUALLY PRESENT IN AN END-USER
#     INSTALLATION ON WINDOWS.
