+
+Chiplotle is a Python library that implements and extends the HPGL
+(Hewlett-Packard Graphics Language) plotter control language. It
+supports all the standard HPGL commands as well as our own more complex
+"compound HPGL" commands, implemented as Python classes. Chiplotle also
+provides direct control of your HPGL-aware hardware via a standard
+usb<->serial port interface.
+
+Chiplotle has been tested with a variety of HPGL devices from various
+companies, including Hewlett-Packard, Roland Digital Group, Houston
+Instrument, etc. It includes plotter-specific configuration files for
+many different plotter models, as well as a generic configuration that
+should work with any HPGL-compliant device.
+
+Chiplotle is written and maintained by Victor Adan and Douglas Repetto.
