# It is useful for a postprocessor to be able to either skip writing out

# formatted for output. If the gcode string is zero length then a zero
# length file will be written out. If the "gcode" variable contains None
# instead, that indicates that the postprocessor doesn't want a file to be
# written at all.
#
# There is at least one old-style postprocessor that currently puts the
# gcode file out to a file server and doesn't need to write out a file to
# the system where FreeCAD is running. In the old-style postprocessors the
# postprocessor code decided whether to write out a file. Eventually a
# newer (more object-oriented) version of that postprocessor will return
# None for the "gcode" variable value to tell this code not to write out
# a file. There may be other uses found for this capability over time.
