+# Description: Toggle mount status of a device using pmount
+#              If the device is not mounted, it will be mounted.
+#              If the device is mounted, it will be unmounted and powered down.
+#
+# Dependencies: lsblk, pmount (optional), udisks2
+#
+# Usage: Runs `lsblk` on 'l', exits on 'Return`.
+#
+# Notes:
+#   - The script uses Linux-specific lsblk to list block devices. Alternatives:
+#       macOS: "diskutil list"
+#       BSD: "geom disk list"
+#   - The script uses udisksctl (from udisks2) to power down devices. This is also Linux-specific.
+#     Users on non-Linux platforms can comment it and use an alternative to power-down disks.
+#
+# Shell: POSIX compliant
+# Author: Arun Prakash Jana
