[texhax] LaTeX3e manual?

[Karl Berry]

    just a quick question - does the LaTeX3e manual exist?

No.

    LATEX: Structured documents for TEX
    unofficial LATEX reference manual
    version 2.0, June 2008

FWIW, I made another release in September 2009.

(And I still welcome help with the project,

Others have already explained the story on \centerline ...

Best,
