XXXX

	This program was written for a friend who was printing up raffle
	tickets on his ST with PageStream.  It will search through a
	file and replace a sequence of XXXXs with an incremental counter.

	usage: xxxx filename.ext -start -count -numberofx -duplicates
	
	e.g. from mupfel or gulam:

	xxxx filename.doc -1000 -250 -4 -2

	will replace 250 sequences of 4 'X's with a counter starting at
	1000 and going through 1249.  Actually 500 replacements will be
	done since duplicates is set to 2.  My friend had a stub and
	a name/address form so each had to be numbered the same.

	('xxxx filename.ext' will default to the those values - 1000,250,4,2).

	'xxxx' will return instructions.

	Nitty gritty: if there are not enough sequences of 'X's, new files will
		be created.  e.g. my friend had 5 pages of 3 tickets in a
		file called raffle.doc - the output of XXXX was into sixteen
		files called raf000.doc - raf015.doc, since 16*5*3 >= 250.
