# Tiled-WM-like-terminal launcher
#
# How to use?
#
# Bind the following command to you favourite key combination
# in your favourite WM. It will execute your favourite terminal
# and when it will connect to X server, it will call this script
# to resize all windows on current desktop in Tiled-WM-like manner
# and run shell specified in SHELLCMD
#
# xterm -e <path to>/tile.sh -ls;<path to>/tile.sh
#
# the -ls will run shell after tiling, and being
# run with arguments, it will just tile windows,
# so when terminal closes, no empty space will be left
#
# Note:
# Currently resize is a bit widescreen-centric and expects dx > dy

SHELLCMD="/bin/bash -l"
