Subject: How can I get the Ruby version from within a Ruby script?

I want to log the current Ruby version to a log file along with the
script version, but I don't know how to get the Ruby version from
within a running script.

I tried:
   puts system("ruby -v")

but that only returns "true" from within a script.  (I see the correct
output when I run it in IRB, but the script doesn't capture that.)

I also tried :
   puts Config::CONFIG["ruby_version"]

but that returns "1.8" and I would like "1.8.x".

Any suggestions?  Please let me know.  Thanks.
