[GRASS-user] can I access mapset outside of grass, by using python?

[Nikos Alexandris]

Apologies for a second post with the code. Just to make it easier to
read/ understand what I've changed.

-- slightly modified code --

strippath()
{
    (
    oldpath="$1"
    newpath=
    IFS=:
    for dir in $oldpath ; do
        case "${dir}" in
        *grass*)
                ;;
        *)
                newpath="$newpath:$dir"
                ;;
        esac
    done
    echo "${newpath#:}"
    )
    unset IFS
}

export PATH="$GISBASE/bin:$GISBASE/scripts:`strippath $PATH`"
export LD_LIBRARY_PATH="$GISBASE/lib"
export PYTHONPATH="$GISBASE/etc/python"
