-.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 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 .
-If a
-.BI -screen
-argument follows a
-.BI -parent
-argument, this screen is embedded into the given window.
-.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 negligible.
-.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 orientated display. Debug mode will
-therefore not be of much use rotated.
-.IP \(bu 2
-The '-host-cursor' cursor is static in its appearance.
-.IP \(bu 2
-The build gets a warning about 'nanosleep'. I think the various '-D'
-build flags are causing this. I haven'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 won't work.
