# How to update mmd_tools: (outdated, no longer used)
# Delete mmd_tools_local folder
# Paste mmd_tools folder into project
# Refactor folder name "mmd_tools" to "mmd_tools_local"
# Move mmd_tools_local folder into extern_tools folder
# Search for "show_backface_culling" and set it to False in view.py
# Done

# How to update google_trans_new:
# In google_trans.py comment out everything that has to do with urllib3
# This is done because 3.5 doesn't have urllib3 by default and it is only used
# to suppress debug logs in the console
# Done

# How to update googletrans:  (outdated since a new googletrans is used Todo remove this)
# in the gtoken.py on line 57 update this line to include "verify=False":
# r = self.session.get(self.host, verify=False)
# In client.py on line 42 remove the Hyper part, it's not faster at all!
# Just comment it out.
# Also see pull request for TKK change
# Also wm progress in client.py
# Done
