# * Script

# No matter what I try, xdotool is not working properly to focus/raise/select
# a window.  And for some bizarre reason, the "xdotool selectwindow" command
# outputs a completely different window ID than "xdotool search" outputs.  In
# fact, the window ID it outputs does not even appear in the output of
# "xprop" for that window.  I have no idea where it's getting that ID.

# So rather than cleanly selecting the proper window in the script, we have to
# do a hacky workaround by sleeping and checking the name of the active
# window.
