In the absence of any definitive statement from the developers that LuaTeX will be compiled with LUA 5.2 for the remainder of eternity, I continue to believe that JFBU is very wise in wishing to be able to easily check which version.

Hi Phil and Norbert,

thanks for the kind help. JFBU indeed thinks luatex is deficient
into not being able to inform straightforwardly the user about
a core component as "lua -v" would do,
but JFBU also thinks that Luatex is never going to become a part
of his future either.

Thanks again,

Jean-François
