-/** @file mged/hideline.c

- * Takes the vector list for the current display and raytraces along
- * those vectors. If the first point hit in the model is the same as
- * that vector, continue the line through that point; otherwise, stop
- * drawing that vector or draw dotted line. Produces Unix-plot type
- * output.
- *
- * The command is "H file.pl [stepsize] [%epsilon]". Stepsize is the
- * number of segments into which the window size should be broken.
- * %Epsilon specifies how close two points must be before they are
- * considered equal. A good values for stepsize and %epsilon are 128
- * and 1, respectively.
