To solve the (in)compatibilities between Omega and e-TeX in the 
versioning system, Aleph comes with a whole BUNCH of version 

\OmegaVersion returns the string 1.15
\AlephVersion returns the string 0-rc3

\eTeXversion returns the *number* 2
\Omegaversion returns the *number* 1
\Alephversion returns the *number* 0

\eTeXminorversion returns the *number* 1
\Omegaminorversion returns the *number* 15
\Alephminorversion returns the *number* 0

\eTeXrevision returns the string .1
\Omegarevision returns the string .15
\Alephrevision returns the string rc3

Note that this doesn't break backwards compatibility with any 
of Omega or e-TeX, so we may want to ask Peter to add 
eTeXminorversion to eTeX?

IIRC, it is also consistent with version numbers in pdf-TeX.
