+.SH NAME
+Xephyr - X server outputting to a window on a pre-existing X display
+.SH SYNOPSIS
+.B Xephyr
+.RI [\fB:\fP display ]
+.RI [ option
+.IR ... ]
+.SH DESCRIPTION
+.B Xephyr 
+is a a kdrive server that outputs to a window on a pre-existing
+'host' X display. 
+Think 
+.I Xnest 
+but with support for modern extensions like composite, damage and randr. 
+.PP
+Unlike 
+.I Xnest 
+which is an X proxy, i.e.  limited to the capabilities of the host X server, 
+.B Xephyr 
+is a real X server which
+uses the host X server window as "framebuffer" via fast SHM XImages.
+.PP
+It also has support for "visually" debugging what the server is
+painting.
+.SH OPTIONS
+.TP 8
+.BI -screen " width" x height
+sets the screen size.
+.TP 8
+.BI -parent " id"
+uses exiting window
+.I id .
+.TP 8
+.B -host-cursor
+set 'cursor acceleration':
+The host's cursor is reused. This is only really there to aid
+debugging by avoiding server paints for the cursor. Performance
+improvement is negiable.
+.SH "SIGNALS"
+Send a SIGUSR1 to the server (e.g. pkill -USR1 Xephyr) to
+toggle the debugging mode. 
+In this mode red rectangles are painted to
+screen areas getting painted before painting the actual content. 
+The
+delay between this can be altered by setting a XEPHYR_PAUSE env var to
+a value in micro seconds.
+.SH CAVEATS
+.PP
+.IP \(bu 2
+Rotated displays are currently updated via full blits. This
+is slower than a normal oprientated display. Debug mode will
+therefore not be of much use rotated.  
+.IP \(bu 2
+The '-host-cursor' cursor is static in its appearence. 
+.IP \(bu 2
+The build gets a warning about 'nanosleep'. I think the various '-D'
+build flags are causing this. I havn't figured as yet how to work
+round it. It doesn't appear to break anything however. 
+.IP \(bu 2
+Keyboard handling is basic but works. 
+.TP \(bu 2
+Mouse button 5 probably wont work.
