Release Name: 1.3.3

Notes:
== What is Utilrb ?
Utilrb is yet another Ruby toolkit, in the spirit of facets. It includes all
the standard class extensions I use in my own projects like Genom.rb.

== Installation
The only dependency Utilrb has is flexmock if you want to run tests. It is
available as a gem, so you can run

  gem install flexmock

== Utilrb's C extension
Utilrb includes a C extension in ext/. It is optional, but some of the
functionalities will be disabled if it is not present. Trying to require
a file in which there is a C-only feature will yield a warning on STDOUT.


Changes:
=== Version 1.3.3

* fixed a problem with WeakRef crashing on 1.8.7p172. This version of weakref
  should now work on every versions of 1.8.6 and 1.8.7
* made ColumnFormatter more configurable
* made the Rakefile callable with ruby's binaries that are not called 'ruby'
