[Roberto Fernández Bautista <roberto.fer.bau@xxxxxxxxx>]

Dear Wayne,

Thanks for taking the time to look at this. However, I should credit Seth
for the hard work he has put on the document to get it to the shape it is
in now - thanks Seth!

I've made you editor now - feel free to edit directly. I suppose I should
make everyone from the lead development team an editor of this document -
could you send me a private email with their email addresses, so I can add
them?

Roberto.
