render_rmrl.py

#!/usr/bin/python3

# This method uses the third-party renderer rmrl to render reMarkable documents locally on the computer.
# It downloads the raw reMarkable files to the computer and renders them locally.
#
# It requires the Python module rmrl (https://github.com/rschroll/rmrl/) and SSH access to the reMarkable (to download the raw files), but no USB connection.
# It is not extensively tested, and fails in some cases.
#
# Thanks to Ph-St for contributing this renderer (https://github.com/hersle/rmirro/issues/10)!
