	The easiest way is with a script such as that provided in
	the X sources in util/scripts/ximake.sh.  However, we had
	a minor problem with this script.

	We use a separate shadow tree as a build tree, with symbolic
	links to files in the original source tree.  In part, we
	want to avoid modifying the original source tree files.
	The original script followed the symbolic link for Makefile
	back to the source tree and updated the wrong tree.

	To cure this we inserted these lines in the script & called
	it just ximake:

35a36,40
> if [ -f $what ]; then
>     cp $what $what.bak                #  Break symbolic link, if any
>     rm $what
> fi

	(Sorry, HP-UX doesn't include cdiff)

	Normal procedure to use it is...

		setenv xs	<root directory of build tree>
		cd  		<directory where you want to do the Imake>

		ximake $xs


	Since it's short, I'll append the modified script to this message.
