# Additional notes:

# To get python arg completion, the following packages are needed 
# argcomplete
# Then this command needs to be executed to register into zshenv `activate-global-python-argcomplete`

# To get rclone tab complete, 
# sudo rclone genautocomplete zsh
# Also if not done before, `/usr/share/zsh/vendor-completions` folder needs to be manually created.
