Automating generation of static documents on github

I know that many of you think that having the editor's drafts rely upon
ReSpec is okay, but we get complaints from users who rely upon assistive
technologies that it is unacceptable / unworkable for them.  The PFWG has
been using gh-pages to present static versions of documents, but has been
generating them by hand.  Can anyone suggest a convenient way, maybe using
Travis, to automate generation of a static gh-pages version when the master
is updated?
