+cncmap - Collection of utilities for milling uneven 2D surfaces
+===============================================================
+
+Overview
+--------
+
When milling a surface, we have the following parameters that depend on
machine configuration and the piece:

+zmap: project points or lines onto the surface defined by a Z map.
+If using a file (read from standard input), that file is in 2D or 3D

+
+spool: send a file to a Roland MDX-15/20 mill. (To do: progress
+reporting, halt and resume, maybe manual mode a la millp.)
+
+
+Formats
+-------
+
+We call the gnuplot-compatible 2D/3D format simply "gnuplot". In gnuplot
+format, each line of the file contains two (X, Y) or three (X, Y, Z)
+coordinates specifying a point.
+
+A polyline is defined by two or more points, followed by at least one
+empty line or any number of empty lines followed by the end of file.
+
+All polylines describe a milling operation. To move the head quickly
+to a new position, end the polygon and start a new polygon at the
+new location.
+
+The gnuplot format does not carry additional information, such as the
+maximum speed of head movements. It may contain comments intended for
+human readers, which consist of a line beginning with an exclamation
+mark. Such lines are ignored and not considered polyline separators.
+
+RML is Roland's proprietary extension of HP-GL. A more or less
+accurate description can be found here:
+http://www.cs.uml.edu/~fredm/lab/egx300/RML1_Command_GuideENVer100.pdf
