It would be essential to have such a spec, even if we ended up having to
change the spec as we went along.

I've never done anything like that before.  Sorry if it has appeared
that I was just being awkward.  I do have a (probably working)
earphones/microphone combination, though.  I think I'll ask on the
Gentoo list if anybody knows what might have happened to my Firefox
Hello.

Is the emphasis on "at the moment" or on the "I'm having difficulties"?
If the former, hopefully the person who committed the build-breaking
commit will fix it.

If you've been so preoccupied by the duties of maintainer that you
haven't yet got a build to succeed, here are some tips:

1. The process is described in INSTALL.REPO in our top level directory.
2. This process is basically:
  (i) From the top level directory ...
  (ii)  ./autogen.sh
  (iii) ./configure    # You can put options here, such as for
                       # debugging, or a host of other things.
  (iv) make -j5 bootstrap # This step is critical the first time you
                          # build a repository.  The "-j5" is for the
			  # number of make jobs you have running at a
			  # time.  Recommended: # of cores + 1.
  (v) make -j5            # For the second and subsequent times you
                          # build.
3. The executable "emacs", hard-linked to "emacs-25.0.50.n", ends up in
the src directory.  To run it, just type "src/emacs -Q" (or whatever).
