[Dev-luatex] pdftexversion, OmegaVersion etc.

I was wondering, since luatex is not a direct replacement of pdftex, omega or aleph, what is the point of having such primitives? Wouldn't it be more cleaner of they are removed or is there any use for them? pdftexversion pdftexrevision OmegaVersion AlephVersion Alephminorversion Alephrevision Alephversion Omegaminorversion Omegarevision Omegaversion eTeXVersion eTeXminorversion eTeXrevision eTeXversion Regards, Khaled -- Khaled Hosny Arabic localiser and member of Arabeyes.org team Free font developer
