--overwrite
    Allow output files to overwrite existing files

--help
    Print usage summary

--verbose
    Verbose module output

--quiet
    Quiet module output

--ui
    Force launching GUI dialog

  Parameters:

input=name [required]
    Name of input file (or "-" to read from stdin)

output=name [required]
    Name for output vector map

separator=character
    Field separator
    Special characters: pipe, comma, space, tab, newline

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.
