How to print Ruby's version from within the program

Is there a way to print the Ruby version from within a Ruby program?

I know i can use ruby -v at the command line, but what if it is inside
of the code and i want to print it out.

this is such as when in TextMate, i want the program to show whether it
is running under Ruby 1.8.2 or 1.8.6

RUBY_VERSION
=> “1.8.6”

TextMate shows the version and location of the used Ruby interpreter
above the program output.

patchlevel = " patchlevel #{RUBY_PATCHLEVEL}" if defined?
RUBY_PATCHLEVEL
version = “ruby #{RUBY_VERSION} (#{RUBY_RELEASE_DATE}#{patchlevel}) [#
{RUBY_PLATFORM}]”

Is the string ruby -v prints out.
