is for all modules to be read only.

+will be able to download files or not. If "write only" is true then any
+attempted downloads will fail. If "write only" is false then downloads

dit(bf(list)) The "list" option determines if this module should be
listed when the client asks for a listing of available modules. By
setting this to false you can create hidden modules. The default is
was run as root. This complements the "uid" option. The default is gid -2,
which is normally the group "nobody".
-dit(bf(exclude)) The "exclude" option allows you to specify a space
-separated list of patterns to add to the exclude list.

the server: that is, it excludes files received by a client when receiving
from a server and files deleted on a server when sending to a server, but

system. The usernames may also contain shell wildcard characters. If

dit(bf(refuse options)) The "refuse options" option allows you to
