#- hc_notify.sh 2015/01/06 cev, last updated 2021/12/07.
## Usage: hc_notify.sh [-hV] [-t timeout] [-u urgency] command <args ...>
##  
##     Execute herbstclient(1) command and signal the user via dbus
##     notification. Valid commands are: close, cycle_layout, floating,
##     fullscreen, move_index, pseudotile, remove, split, use_index.
##  
##       -h     Show help options.
##       -t     Notification timeout (notify-send -t)
##       -u     Notification urgency (notify-send -u)
##       -V     Print version info.
## 
#
#  Simple wrapper script around herbstclient(1). Executes hc command,
#  then notifies the user of the action taken using dbus / notify-send.
#
#  This could use some updating.
