why is e.g. web2c in the texmf tree?

[K. Berry]

    If E. Mattes suddenly came along 
    with an official recommendation for the organization of TEXMF/emtex, 
    we'd be happy to add another subsection, but if he prefers to keep
    his binaries/formats/bases outside the TEXMF tree that's OK as well.

Even if he prefers to keep outside of TEXMF, we'd be happy to add a
subsection :-).
