This command creates directory directoryname on remote server host. The directoryname must
not begin with a slash. It should normally begin with the value of
property PICSDIR, so the directory is within the site pages. The named directory and any not-previously-existing parents are
all created on
the host.
The ftp password for username must be supplied, ideally as the value of environment variable PICPASS. See the description of property picpass.
