#!/bin/sh
# xvfb-run - run the specified command in a virtual X server

# This script starts an instance of Xvfb, the "fake" X server, runs a
# command with that server available, and kills the X server when
# done.  The return value of the command becomes the return value of
# this script.
#
# If anyone is using this to build a Debian package, make sure the
# package Build-Depends on xvfb, xbase-clients and xfonts-base.
