"""
Open the 'url' in the current desktop's preferred file browser. If the
optional 'desktop' parameter is specified then attempt to use that
particular desktop environment's mechanisms to open the 'url' instead of
guessing or detecting which environment is being used.
Suggested values for 'desktop' are "standard", "KDE", "GNOME", "XFCE",
"Mac OS X", "Windows" where "standard" employs a DESKTOP_LAUNCH environment
variable to open the specified 'url'. DESKTOP_LAUNCH should be a command,
possibly followed by arguments, and must have any special characters
shell-escaped.
The process identifier of the "opener" (ie. viewer, editor, browser or
program) associated with the 'url' is returned by this function. If the
process identifier cannot be determined, None is returned.
An optional 'wait' parameter is also available for advanced usage and, if
'wait' is set to a true value, this function will wait for the launching
mechanism to complete before returning (as opposed to immediately returning
as is the default behaviour).
