@item{GRacket, which is a GUI variant of @exec{racket} to the degree
that the system distinguishes them. Under Unix, the executable
is called @as-index{@exec{gracket}}, and single-instance flags
and X11-related flags are handled and communicated specially to
the @racket[racket/gui/base] library. Under Windows, the
executable is called @as-index{@exec{GRacket.exe}}, and it is a
GUI application (as opposed to a console application) that
implements singe-instance support. Under Mac OS X, the
@exec{gracket} script launches @as-index{@exec{GRacket.app}}.}
