Could we instead build them from source?

I understand that building the PDF/PS would require an extra dependency
on TeX Live.  This could be:

  1. ignored, on the grounds that people with substitutes enabled will
     not have to download TeX Live; or:

  2. addressed by having only the HTML documentation built, on the
     grounds the HTML is more appropriate for on-screen reading.

WDYT?
