# Modification History

# Changed on 16/12/31 by Jaimos Skriletz:
# - Added check for FVWM_USERDIR env variable.
# - Added check for python-xdg module to print less errors if not found.
# - Added option -e/--menu-error to output phython-xdg not found as
#   a menu for the default-config.

# Changed on 16/10/27 by Jaimos Skrietz:
# - Renamed default menu to XDGMenu and changed the name of the
#   FvwmForm to FvwmForm-XDGMenu-Config
# - Modified the FvwmForm and added the abilty to load defaults from
#   the Form's data file.
# - Changed default to generate menu titles. Disable with --without-titles
# - The top level menu now has two additional items:
#     'Regenerate' - Regenerates menu.
#     'Configure' - Opens up FvwmForm-XDGMenu-Config.
# - Added --regen-cmd "CMD" for a fvwm CMD to use on the Regenerate item.
#   Default: PipeRead `fvwm-menu-desktop`
# - Added --include-items [config|regenerate|both|none] option
#   to control if the additional items are included in the menu.
# - Added --dynamic option to be used with dynamic menus.
# - Added --all-menus option to generate all menus and not try to determine
#   which one is best
# - Changed default behavior to include menu titles.
# - Added new option --without-titles

# Changed on 25/02/14 by Thomas Funk:
# - Converting of icons always to png

# Changed on 06/10/13 by Thomas Funk:
# Some Bugfixes:
# - DecodeEncodeErrors in menu names
# - no output appears with 'fvwm-menu-desktop --get-menus all|desktop'
# - No entry "Regenerate XDG menu(s)" appears with
#   'fvwm-menu-desktop --insert-in-menu MenuRoot'
# - exchange all tabs with spaces to prevent indention errors
# - add two new options: --app-icon --dir-icon
#   to handle default icons for not available app/dir icons
# - fix bug in convert icon routine that background of svg icons are
#   transparent

# Changed on 15/06/13 by Thomas Funk:
# support for python-xdg > 0.19.
# add gettext localization.

# Changed on 10/01/12 by Thomas Funk:
# Unicode support.

# Changed on 01/26/12 by Dan Espen (dane):
# Make compatible with fvwm-menu-desktop.
# Restored DestroyMenu, needed for reload menus.
# Remove bug, was printing iconpath on converted icons
# Replace obsolete optparse, use getopt instead
# Change from command line arg for applications.menu
# change to using ?$XDG_MENU_PREFIX or theme? fixme
# - use "Exec exec" for all commands, remove option.

# fixme, fix documentation, FvwmForm-Desktop, usage prompt is wrong
# change, mini icons are enabled by default.
# there are rescalable icons.
