Kernel::VERSION

[Bret Jolly]

There used to be a constant of this name, which I was using
in programs to figure out which version of Ruby the user had.
It seems to be gone in Ruby version 1.8.1. What should I
use instead?

Regards, Bret

$ irb
irb(main):001:0> VERSION
=> "1.8.1"
irb(main):002:0> Kernel::VERSION
NameError: uninitialized constant Kernel::VERSION
from (irb):2

Looks like it's just not Kernel::VERSION.

RUBY_VERSION works too.

RUBY_VERSION works too.

Thanks. RUBY_VERSION looks good and works as early
as ruby 1.6.4 (the earliest version that builds on my
machine).
