       --verbose
           Verbose module output

       --quiet
           Quiet module output

   Parameters:
       input=string
           Name of input file (or "-" to read from stdin)

       output=string
           Name for output vector map

       fs=character
           Field separator
           Default: |

DESCRIPTION

       Imports a stream of ASCII x,y[,z] coordinates as a line or series of lines.

NOTES

       Input  ASCII  coordinates  are  simply  a  series  of  "x  y"  data points.  Lines are separated by a row
       containing "NaN NaN".

       The user can import 3D lines by providing 3 columns of data in the input stream and using the -z flag.

       This script is a simple wrapper around the v.in.mapgen module.
