Notes on UPGRADING from a previous release of HOWITZER (0.83beta or
earlier):

*	You can safely unpack the new version of Howitzer in your
	old Howitzer directory - nothing important will be overwritten.

*	The format of HOWITZER.INI has changed.  It's now much more
	readable, but completely incompatible with older versions.
	You should delete your old HOWITZER.INI before running the
	new version of HOWITZER.

*	Registration datafiles from older versions of Howitzer work
	just fine with the new version.  Make sure Howitzer and the
	datafile are in the same directory; this copy of Howitzer
	will then enable all cheat features.

*	Read the documentation!  A _LOT_ has changed since 0.84beta.

*	0.90beta will NOT expire after a certain date.
