Toggle global EDE (Emacs Development Environment) mode.
With a prefix argument ARG, enable global EDE mode if ARG is
positive, and disable it otherwise. If called from Lisp, enable
the mode if ARG is omitted or nil.
This global minor mode enables `ede-minor-mode' in all buffers in
an EDE controlled project.
(fn &optional ARG)
Non-nil if Global-Ede mode is enabled.
See the command `global-ede-mode' for a description of this minor mode.
Setting this variable directly does not take effect;
either customize it (see the info node `Easy Customization')
or call the function `global-ede-mode'.
