Use the tools to demonstrate your skills. It carries more weight than
just saying you know them.

PS - Bonus points for a one-line encoder that encodes the same
original string from the source.
PPS - Extra bonus points for pointing out a bug in the above
implementation.  I know of at least one.
PPS - I considered attempting to use all of the commands in his
subject, and no others, but working in man and toe proved overly
cumbersome or superfluous.  It's a trifecta if you can also provide a
non-contrived example that does that.
PPPS - Yes, you could do it all with perl, but that'd be cheating.
