Why *Ruffus*?
###############################

**Cylindrophis ruffus** is the name of the
`red-tailed pipe snake <http://en.wikipedia.org/wiki/Cylindrophis_ruffus>`_ (bad python-y pun)
which can be found in `Hong Kong <http://www.discoverhongkong.com/eng/index.html>`_ where the original author comes from.


*Ruffus* is a shy creature, and pretends to be a cobra or a `banded krait  <http://en.wikipedia.org/wiki/File:Bandedkrait.jpg>`__ by putting up its red tail and ducking its
head in its coils when startled.

Be careful not to step on one when running down country park lanes at full speed
in Hong Kong: this snake is a `rare breed <http://www.hkras.org/eng/info/hkspp.htm>`_!

*Ruffus* does most of its work at night and sleeps during the day: typical of many (but alas not all) python programmers!
