 I created a basedir with {{{tahoe create-client ${BASEDIR}}}}, then
 started the client with {{{tahoe start ${BASEDIR}}}, then ran {{{tahoe
 mkdir -d ${BASEDIR}}}}, and it did this:
 {{{
 $ tahoe mkdir -d .

 There is no {{{node.url}}} file present. The usage information from
 {{{tahoe mkdir --help}}} makes it sound like the {{{node.url}}} file is
 not necessary if the actual Tahoe-LAFS gateway is there:
 {{{
   -d, --node-directory=   Specify which Tahoe node directory should be
 used. The
                           directory should either contain a full Tahoe
 node, or
                           a file named node.url that points to some other
 Tahoe
                           node. It should also contain a file named
                           'private/aliases' which contains the mapping
