I would say 'busybox'.

Basically, you've got the source code to a hundred useful programs,
but each one of them has been stripped down to the bare essentials.

Compare the length of the source code for GNU 'true' with busybox's
'true'. Ditto 'false'. Ditto 'yes'. Etc. etc. ...

Don't think busybox's programs are functional enough? Great - that's 
your programming exercise!

Unfortunately, the maintainers of busybox do include hackish 
microoptimisations simply because they make the x86 binaries
shrink, with no care for the portability of the optimisation.
(I've not checked, maybe it's because all other architectures
are carp, that's a common excuse.)
