No, it would be "BSD licensed iff". :-)

Err... nothing. Or rather, I'm not sure what it stands for. I was
looking for a name for a diff tool which worked on "binary software" (or
more generally, files with lots of "byte-substitutions"), and which uses
"bytewise subtraction" as part of its encoding process... (I'm sure you
can think of other possible meanings of "bs", as well.)

When I first wrote this code, I called it "bdiff". Soon thereafter, it
was pointed out to me that there was a bit of a namespace collision -- the
name "bdiff" -- and the name "bindiff", which was my second choice -- had
each been used for several different (not very good) binary diff tools
So I looked for a name which hadn't already been used by several other
people, and settled on "bsdiff" / "bspatch" as a compromise between being
descriptive and avoiding the possibility of getting confused with another
This is all rather immaterial at this point, however: It's far too late
to change the name now.
