# Gives a dmenu prompt to mount unmounted drives and Android phones. If
# they're in /etc/fstab, they'll be mounted automatically. Otherwise, you'll
# be prompted to give a mountpoint from already existsing directories. If you
# input a novel directory, it will prompt you to create that directory.
#File should have two fields: uuid and password location in pass
#The file is tab-seperated
#UUIDs can be found via `lsblk -rpo "name,size,uuid"`
