Gopherus is a free, multiplatform, console-mode gopher client available for
DOS, Linux and Windows. It provides a classic text interface to the
gopherspace. Altough primarily targeted for DOS, ports to Windows and Linux
are also available. These use SDL to emulate a pseudo terminal.
This program is released under the terms of the GNU GPL v3 license. See the
license.txt file for details.

 variable have to contain exacty 6 color attributes. Each attribute describes
 the foreground/background color for a given element of the Gopherus user

  Missing those green 1980-like phosphor CRTs?..: "022020202002020220"


 *** Requirements ***

 Gopherus has been designed with hardware sparseness in mind, hence it doesn't
 need much to run. But still, the DOS version requires at least:
  - a CGA card
  - 80386SX CPU
  - 1M of available RAM
  - an ethernet card with a working packet driver
  - a DPMI environment (like CWSDPMI.EXE)


 *** Final notes ***

 Gopherus has been written with care to behave nicely and follow standards.
 It conforms closely to following guidelines:
   RFC 1436: The Internet Gopher Protocol
   RFC 4266: The gopher URI Scheme
