Subject: pry - attach an irb-like session to any object at runtime - 0.6.0 released

pry is an irb-alternative that enables you to open a session on any
object at any point in the running program. It can also be run from the
command line.

Some uses of Pry are in debugging, exploring a codebase, even reading
documentation (using the show-doc and show-method commands (ruby 1.9
only)).

Pry supports a bunch of commands that make it easy to navigate around a
code-base, such as: cd, cat, show-method, and in particular the `ls`
command (see https://gist.github.com/835694)

Pry can also be easily configured to implement custom shells; and it can
be set to read from any object that implements a `readline` method and
output to any object that implements `puts`: (e.g Pry.input =
StringIO.new("puts 'self'\exit"), Pry.output = my_output)

For more information, try the gem: `gem install pry`
And check out the following documentation:
