Some progress on this, but I suspect there's something "under the

The r.in.wms documentation says:
*r.in.wms* [-*ldockp*] [*output*=/string/] *mapserver*=/string/
[*layers*=/string/[,/string/,...]] [*styles*=/string/[,/string/,...]]
[*srs*=/string/] *format*=/string/ [*wmsquery*=/string/]
*maxcols*=/integer/ *maxrows*=/integer/ [*tileoptions*=/string/]
[*region*=/string/] [*folder*=/string/] [*wgetoptions*=/string/]
[*curloptions*=/string/] *method*=/string/ [*v*=/integer/]
[--*overwrite*] [--*verbose*] [--*quiet*]
Note that "mapserver" appears before layers. If I use this syntax, I
get:
ERROR: Required parameter <layers> not set:
(Layers to request from map server).
However, if I reverse the order of the mapserver and the layers:
r.in.wms output=Background layers=psma:all mapserver=<URL>
The parser doesn't really care about the order*; this lends credence to
the theory that you need to quote your strings from the terminal and
the command gets side-tracked with a &|;= before getting to the end.
In the case where layer= comes first it will truncate the mapserver=
option and it will still fail, but later on in the script.
[*] If your mapserver URL contains an unquoted "=" the parser might
treat that part as an option.
- then things work okay. So is it an error in the documentation, or
has a more recent release changed the r.in.wms script?
Did this once work for you in an earlier version of GRASS?
Hamish,
Here's how things stand now.
Quoting properly fixes the problem on Grass-6.3 under Tiger.
However, on Grass-6.3RC4 on Leopard, with the new r.in.wms and
wms.downloads installed, I still get the wms.download error on line
118, that -n is an invalid option...
Cheers,
RC
