The following is the "header" of ``filepatch'' which was posted to alt.sources
recently; the program works fine on all systems upon which I installed it.

	Here is a binary editor that i've found useful. It has only been
	tested in SYSV & SCO XENIX environments, but should be relatively easy
	to port. Do to the non-standard alternate character set mapping prior
	to SYSV3, the line drawing characters are replaced with, |, -, and +
	for those environments (or if your terminal doesn't support line
	drawing charaters).
