This disc contains the X11R6 Window System.  For your convienience,
you get precompiled Sparc binaries for SunOS 5.3 (Solaris) and 4.1.3.
All binaries are runnable directly from the CDROM, so there is no
need to commit disk space to X11R6.  This disc also contains
utilities to allow you to compile the source tree directly from the
CDROM, saving an additional 285 megabytes of filesystem space.

System Requirements:

X11R6 will work on most Unix systems that support bitmapped displays.
The Following is a list of supported and tested platforms:

     A/UX 3.0.1,  AIX 3.2.5,  BSD/386 1.0, HP-UX 9.1, IRIX 5.2,
     Mach 2.5 Vers 2.00.1,  Microsoft Windows NT 3.1,

This disc contains all the X11R6 distribution and the contributed X11
software released on May 2, 1994.  You can even keep an earlier
release of X11 on your system.  X11R6 installs to /usr/X11R6, so it
will not conflict with your previous installations of X11.
