 Hi,

 it would be nice if v.in.mapgen could read directly from stdin when
 'input=-'.

 in "matlab" format mode this module can make a vector line map from a two
 column "x y" data-stream, with new lines created whenever a "nan nan" is
 in the stream. this is very useful for creating a line from points without
 bothering with the grass vector ascii format. it might be worth getting
 its own wrapper script as the 'v.in.mapgen -f' command is not obvious for
 this generic task. v.in.points_as_lines or ...?


 thanks,
 Hamish
