Any chance you want to add a wee how-to to the end of README-DEVEL.txt?  I'm
happy to do this, but would rather not stuff it up :)

Is there any point in retrospectively signing the 1.0 release, or should I
just start this from 1.0.1 and 1.1a1?  (Assuming that I do the next release,
which is probably a reasonable assumption).
