  $ dpkg-query -L tar | grep bin/
  /bin/tar
  /usr/sbin/rmt-tar
  /usr/sbin/tarcat

Checking the $PATH would be clever but the above covers it for me.

There are some insane packages which crap binaries under /usr/lib, such as
/usr/lib/libreoffice/program/oosplash or /usr/lib/man-db/manconv and generally I
consider these packages to be maintained by madmen.

I mean honestly:

  $ cat /usr/bin/7z
  #! /bin/sh
  exec /usr/lib/p7zip/7z "$@"

Why would you do that? Why would ANYONE voluntarily DO that?
