Its also possible to handle this in an inside-out mechansim
using a `zrun` from `sys-apps/moreutils`
---
zrun head -n 1 /usr/share/man/man1/cat.1.bz2

Its a bit of an unusual approach, but can do things where normal pipe become
difficult
How it works becomes quickly apparent:
--
zrun md5sum /usr/share/man/man1/{cat,pr}.1.bz2

Its a nice trick to have up your sleeve :)
