= netdiff =

netdiff performs diff across network links.

Takes two arguments which may be host:path pairs in the
style of ssh/scp, make temporary local copies as needed,
applies diff(1). All options are passed to diff(1).

It's not fast over large trees, but quite useful if you
need to (for example) diff /etc across hosts on a LAN.

Written in pure POSIX shell; no dependencies other than
scp(1) and diff(1),
