It's extremely trivial to verify archives in many cases (or even all
cases provided you have lots of free space for temporary files as big as
your archive) without any special non-"standard" options:
tar -cf foo.tar foo
tar -cf - foo | cmp - foo.tar
(this doesn't seem to work for compressed archives, but then if you're
compressing things you probably don't care as much about integrity :-)

"cd /usr/pkgsrc/archivers/gtar; make install clean-depends clean" :-)
