HPGL is the language to control pen plotters by HP, like the 7475
series. It is
a 2-D format, with no true spec for velocity. It is fine for most
engraving
work, but has no real applicability to machining with 3 axes, tools with

non-zero diameters, need to control feed rates and spindle speeds, etc.
