Manage a OOo server: start, stop and unlisten.
If you want a full-blown server, help enhancing this script! See
source for comments.
Some ideas taken from Dag Wieers unoconv

"""
# Todo:
#
# * Implement a full-blown deamon for Unix and a full-blown service
# for Windows. Should this restart OOo automatically if it crashed?
#
# * Design issue: OOo behaves different depending whether there is
# already an instance running: If one it running, the new process
# returns. If there is no instance running yet, he new porcess will
# _not_ return. But how determine whether the server started
# successfully or there has been an error?
