# (only kidding, it's not copyrighted. Do whatever you like with it)
#
# This pipe menu creates an application menu from the .desktop files
# found in many linux distributions. The desktop file must be of type
# Application and specify their Categories.
# 
# One or more paths to search may be provided on the command line or
# specified below. The menu structure is derived from the Categories
# attribute and may be customised below with the following keywords:
# 
# hide:     menu will not be displayed
# collapse: the submenus will be used instead
#
# Any item starting with X- is automatically hidden
