Getting the version number of the ruby interpreter

Keith P. Boruff

Hello all,

Is there a way to get the version number within a ruby script of the
interpreter running that script?

Yes, I know I can do this on the cmd line:
% ruby --version

I didn't seem to find anything in the documentation though I am new at
this language.

I have my reasons for wanting the version info in this manner. If you
really want to know, I'll tell you. Otherwise, I'll spare you the boring
details.

Thanks,
KPB

Note that the constant VERSION has been obsolete. Use
RUBY_VERSION instead.
