Using "split" was closer in spirit to the UN*X way of doing things.  I
ended up using "dd" to break the file into two chunks, each of which
would comfortably fit on a CD.

Example:
	dd if=huge_file of=chunk.0 bs=1K count=500K
	dd if=huge_file of=chunk.1 bs=1K skip=500K

gives you a 500MB chunk.0 file, with the remainder going into chunk.1.
Putting Humpty Dumpty back together again is as simple as

	cat chunk.0 chunk.1 > huge_file

once the pieces have been retrieved from their respective CDs.
