0.1.2
* Now check for a .onexit as well.
* Unset ONDIRWD variable after scripts have executed.
* Added a config file /etc/ondirrc or ~/.ondirrc that contains directories and 
  enter/exit scripts. This is the most secure way of having scripts execute and
  is preferred over .onenter and .onleave. See man page for further information.
  Thanks to Darren Chamberlain for this idea.

0.1.1
* Added a patch sent in by Mira Tempr to check for group/other write 
  permissions on the scripts and refuse to run them if they are set.
  Subsequently changed the name of the function to make more sense.
* Added -V to display version.

0.1.0
* Released.
