GOPHER is a network protocol that enables multiple servers
     to create a single, uniform filesystem that transcends system
     architecure and operating systems (GOPHERSPACE).  With GOPHER,
     information holds the most value.  Since presentation is uniform
     across GOPHERSPACE, the user does not encounter any challenges
     in 'learning' a new site.  Because of its simplicity and its 
     emphasis on the importance of informational texts, GOPHER is
     ideal for those who are visually impared.
     A GOPHER client can be called from SDF by typing 'gopher'.  A URL
     (Uniform Resource Locator) can be given as an argument.  The client
     itself is a document examiner.  You can use it to search text documents
     or download files.  Clients under X11, Macintosh and other systems 
     can view pictures, and stream audio / video.
     Many people think the http protocol has deprecated gopher, but that
     just isn't true.  Where do you think GOPHERs live?  underground.

     When you build your GOPHERSPACE on SDF, you are contributing to an
     underground network of systems that still believe in the gopher
     protocol.  There is no commercialism, no banner ads, no spam, no
     pop-up ads.  GOPHER gives you what you want: information and files
     (in any form) without the silliness of HTML and clumsiness of websites.
     No HTML development is needed to contribute to GOPHERSPACE.. since
     sites are uniform, all you need to do is upload or create your files.
