NAME
     Xapollo - X window system Apollo implementation notes

DESCRIPTION
     The Apollo X server can be started as a command to /bin/csh.
     It requires two arguments, both of which should be 0.  Nor-
     mally, however, the server should be started by invoking
     _x_i_n_i_t(1).

     The device dependent portion of the server is implemented
     using GPR system calls, and is known to work on DN300,
     DN330, DN560, DN660, and DN3000 systems,  all running SR9.2.

BUGS
     Restrictions in the current implementation:

     -    Brush shapes are ignored and all result in 1x1 brush.

     -    The labelled control and shift keys do not affect the
          mouse buttons;  the keys LD, LE, and LF have been
          pressed into service to provide control, meta, and
          shift, respectively, for the mouse buttons.  The "POP"
          key also serves as a general meta key.  Should the
          server become "wedged", typing shift F8 will terminate
          the server.

     -    Apollo fonts impose restrictions on the number of char-
          acters (127) and their maximum size;  thus, some fonts
          cannot be converted to Apollo format and performance
          using them is badly degraded.  Those fonts that can be
          converted to Apollo format should be converted using
          the cvtfont program.

     -    XY masks (for defining non-rectangular clipping regions
          or "stencils") are not implemented.

     -    No SHIFT LOCK key is implementd.

     -    Only down events are available for the standard "print-
          able" keys.

     -    Up- and Down-events for the normal Control and Shift
          keys are simulated, as these keys do not correspond to
          separate GPR events.

     -    The csh invoking xinit should not have inprocess set.
          This will cause the initial xterm process to hang.
