# Recycle this code: example for dynamic openbox pipe menu:
# This is no a part of the project but is only a funny way for recycle this

#    HOW TO USE:
#    Edit your openbox menu.xml
#    Add a new pipe menu just adding this line:
#       <menu execute="~/.scripts/mylaunchpad-master/ob_pipe_menu.py default All" id="pipe-menu" label="Applications Menu"/>
#
#    *You can change the default menu with your favorite xdg-menu like xfce-applications or lxde-aplications
#    *You can change All with the ID of a specific category
