# ## Conky drive info
#
# Find mounted drives and create a list ready for conky.
# Avoids the dreaded `${if_mounted (path)}` commands.
# Especially helpful in highly dynamic setups.
# Contains protection against empty folders like unmounted NFS-mountpoints.
#
# Usage:
#
# + Copy script to your conky scripts folder, e.g. `~/.config/conky/scripts/
# + Make executable
# + Add an `execp` command to `.conkyrc`
#     + e.g. `${execp $HOME/.config/conky/scripts/media-info.sh}`
# + In the shellscript
#     + Call this function with the folder that contains mounted drives
#     + Works both for dynamically and statically mounted drives
