[GRASSLIST:7126] Re: VMAP to SHAPE

[Markus Neteler]

Dear Masahiro Itamochi,

a proposal for MS-Windows users with broadband internet
access: Since you only want to convert the data a single time,
you may download a KNOPPIX(-derivate) Live-Linux and run the 
proposed scripts there. You can get out the data via network
or USB key.

To run the proposed scripts under DOS is probably more complicated.
