Re: Gtk patch version 3, part 1

[Richard Stallman]

    Anyway, if the document can be automatically converted to Texinfo, as
    Alfred and Alex suggest and if GTK were willing to distribute the
    Texinfo form with the project, then that completely solves the
    problem anyway.

They don't necessarily need to distribute the Texinfo file; it is
enough if they have makefile targets to produce Info and DVI files
from their source files.

But none of that substitutes for writing the text that needs to be in
the Emacs manual.  Pointing to GTK documentation is good for telling
the user where to find more info about GTK, but the essential points
about customizing Emacs should be given in the Emacs manual, focusing
specifically on Emacs, addressed to Emacs users.
