well, I set it to the directory where I checked out the
addons from the SVN repository but it didn't work.
maybe you need to pass wget "localhost" + apache2 or file:// ..?
anyway probably easiest is to just open the script and follow it line by
line and replace wget with cp. If you find a nice way to do that we could
add a new option for svnpath= or something. As you point out it could be
useful.
(for scripts I usually just symlink from their grass-addons svn checkout
home into GRASS_ADDONS_PATH, for C modules I actually build everything
from source)
