          mothra - retrieve World-Wide Web files

          mothra [ url ]

          Mothra retrieves and displays files from the World-Wide Web,
          by name or through hypertext links.  Web names, called URLs,
          have a peculiar syntax:


          The part up to the first colon gives the protocol for
          retrieving the file.  http:, Hyper-Text Transfer Protocol,
          is the usual way of accessing web files.  file: names a file
          in the local file system.  ftp: and gopher: are standard
          Internet services.

          // begins the Internet address of the server where the file
          resides.  The address may contain a colon and a TCP port
          number, which overrides the default port number for the ser-
          vice.  Next comes a file name.  Finally, the file name may
          be followed by # and a string giving a label within the file
          where the display should begin.

          Mothra starts with the url given on the command line,
          defaulting to the environment variable $url, and finally to

          The display contains the last message from mothra, a box
          where typed commands appear, a scrollable list of previously
          visited files, the title and URL of the current file, and
          the scrollable text of the current file.

          Button 1 selects and displays a file, either from the list
          of previously visited pages or from a link (indicated by
          underlined text or a boxed image) in the current file.  But-
          ton 2 shows the URL of a file, but does not retrieve or dis-
          play it.  Button 3 pops up a menu of commands:

          save back  Place a link to the current file in a `back list'
                     for future reference.
          get back   Retrieve and display the back list.

          fix cmap   Adjust the display's color map so that images
                     will have correct colors.
          exit       Ask for confirmation and quit.

          The typed commands are:

          g url      Get the page with the given URL.
          s file     Save the current file in the given file.
          q          Quit.
          h          Get help.

          When mothra retrieves a file that is not an HTML document
          (for example a GIF or JPEG image), it will start up an
          appropriate viewer, for example fb/9v (see 9v(9.1)) for
          image files.

          $home/lib/mothra/mothra.err log of error messages, including
          HTML syntax errors


          ftp: URLs are not supported.
          Files are saved in the form received, not in the form sug-
          gested by the name in an s command.
          Mothra is distributed in a preliminary state; it has more
          than its share of bugs.
