[GRASS-dev] 2nd edition gis book

[infotechsys at pivot.net]

    Hi,
    I'm thinking about purchasing "Open Source GIS" 
    by " Markus Neteler and Helena Mitasova". I notice
    that a new edition is coming out next year. Should
    I wait for the new edition or go ahead and purchase
    the second edition? What is the main differents
    in the two edition? While I'm here, can GRASS read
    Autocad files? My town uses a company that has 
    digitize the town maps using Autocad and I want
    to show them a different way of doing it, hoping
    to save them some money.
    Thanks.
