++	* configure.in:
++	* gnome-version.xml.in.in: add a --disable-date-in-gnome-version
++	configure option to not put the build date in gnome-version.xml. The
++	build date is actually not that useful since it's not the build date
++	for all of GNOME, but for this specific package. So it can be
++	confusing.
++
++2009-03-26  Vincent Untz  <vuntz@gnome.org>
++
++	* gnome-about/gnome-about.in: make the code returning the content of
++	gnome-version.xml a bit more solid, so that we can handle a file
++	that doesn't contain the date, the distributor or the version.
