	DOC_CONTENTS="For copyright reasons, xtrs does not include actual ROM
		images. Because of this, unless you supply your own ROM, xtrs will
		not function in any mode except 'Model 4p' mode (a minimal free ROM
		is included for this), which can be run like this:
		\n\nxtrs -model 4p -diskdir /usr/share/xtrs
		\n\nIf you already own a copy of the ROM software (e.g., if you have
		a TRS-80 with this ROM), then you can make yourself a copy of this
		for use with xtrs, using utilities available on the web. To load
		your own ROM, specify the '-romfile' option, or the 'Xtrs.romfile'
		X resource. ROM files can be in Intel hex or binary format."
