.SH DESCRIPTION
\fIv.to.lines\fR converts vector polygons (boundaries) to lines as well
as vector points to lines via triangulations.
.SH NOTES
\fIv.to.lines\fR is able to convert point data (via triangulation)
and areas to lines (via boundary to line conversion).
This script is a wrapper script to \fIv.category\fR,
\fIv.delaunay\fR, and \fIv.edit\fR.
.PP
In order to convert an ordered list of coordinates (ASCII table with
x,y[,z] coordinates) into vector lines, use \fIv.in.lines\fR.
.SH EXAMPLES
The examples are for the North Carolina sample dataset location:
