Log:
new module: imports x,y[,z] ASCII coodinates as a series of vector lines. after testing & porting to python it should be moved into the main archive.

+<H2>DESCRIPTION</H2>
+
+Imports a stream of ASCII x,y[,z] coordinates as a line or series of lines.
+
+
+<H2>NOTES</H2>
+
+Input ASCII coordinates are simply a series of "x&nbsp;y" data points.
+Lines are separated by a row containing "<tt>NaN&nbsp;NaN</tt>". Line
+categories start at 1 and increase sequentially.
+<P>
+You can import 3D lines by providing 3 columns of data in the input
+stream and using the <B>-z</B> flag.
+<P>
+This script is a simple wrapper around the <em>v.in.mapgen</em> module.
