If you split a binary file using split(1), then just rejoin the parts
with cat(1):

	% split -b 1400000 largefile.bin
	% cat x[a-z][a-z] > largefile2.bin

After these two steps, you should have:

	largefile.bin		The original binary file.

	xaa, xab, ...		Chunks of the original file that can fit
				in 1.4MB floppies (does anyone use these

	largefile2.bin		A second copy of the original file, that
				was created by joining the x[a-z][a-z]
				chunks that split(1) created

After writing this post, I realized that split(1) doesn't have an
EXAMPLES section.  I think we should add one :)
