-.SH NAME
-xcompmgr \- sample X compositing manager
-.SH SYNOPSIS
-.BI "xcompmgr [\-d " display "] [\-r " radius "]"
-.BI "[\-o " opacity "] [\-l " left-offset "]"
-.BI "[\-t " top-offset "] [\-acCfFnsS]"
-.SH DESCRIPTION
-.B xcompmgr
-is a sample compositing manager for X servers supporting the XFIXES, DAMAGE,
-and COMPOSITE extensions. It enables basic eye-candy effects.
-.SH OPTIONS
-.TP
-.BI \-d\ display
-Specifies the display to manage.
-.TP
-.BI \-r\ radius
-Specifies the blur radius for client-side shadows.
-.TP
-.BI \-o\ opacity
-Specifies the opacity for client-side shadows.
-.TP
-.BI \-l\ left-offset
-Specifies the left offset for client-side shadows.
-.TP
-.BI \-t\ top-offset
-Specifies the top offset for client-side shadows.
-.TP
-.BI \-I\ fade-in-step
-Specifies the opacity change between steps while fading in.
-.TP
-.BI \-O\ fade-out-step
-Specifies the opacity change between steps while fading out.
-.TP
-.BI \-D\ fade-delta
-Specifies the time (in milliseconds) between steps in a fade.
-.TP
-.BI \-a
-Automatic server-side compositing. This instructs the server to use the
-standard composition rules. Useful for debugging.
-.TP
-.BI \-c
-Client-side compositing with soft shadows and translucency support.
-.TP
-.BI \-f
-When \-c is specified, enables a smooth fade effect for transient windows like
-menus, and for all windows on hide and restore events.
-.TP
-.BI \-n
-Simple client-side compositing. This is the default mode.
-.TP
-.BI \-s
-Server-side compositing with hard-edged shadows.
-.TP
-.BI \-C
-When \-c is specified, attempts to avoid painting shadows on panels and docks.
-.TP
-.BI \-F
-When \-f is specified, also enables the fade effect when windows change their
-opacity, as with transset(1).
-.TP
-.BI \-S
-Enables synchronous operation. Useful for debugging.
-.SH BUGS
-Probably. Please report any you find to http://bugs.freedesktop.org/.
-.SH AUTHORS
-Keith Packard, with contributions from Matthew Allum, Eric Anholt, Dan Doel,
-Thomas Luebking, Matthew Hawn, Ely Levy, Phil Blundell, and Carl Worth.
