--verbose
Verbose module output
--quiet
Quiet module output

DESCRIPTION
v.in.mapgen allows the user to import Mapgen or Matlab vector maps into
GRASS.
NOTES
This module only imports data into vector lines.
The user can get coastline data in Mapgen or Matlab format from NOAA’s
Coastline Extractor at http://www.ngdc.noaa.gov/mgg/shorelines/shore-
lines.html.
Matlab vector line maps are simply a series of "x y" data points. Lines
are separated by a row containing NaN NaN. Output from Matlab with
this command:
save filename.txt arrayname -ASCII
The user can import 3D lines from Matlab by exporting a 3 column array
and using the -z flag.
