First, we don't have to include the file in our benchmarks.  We could
instead run the benchmarks on it and publish the results.  It isn't
like the implementation of charpos<->bytepos conversions changes too
often.

Second, after looking at the site, I cannot figure out the copyright
issues.  The only place where this is addressed is the following
question in their FAQ:

  3.3  How about copyright issues ?

  Project Madurai strictly adheres to copyright standards.  All the
  works in the collection are either from public-domain (after a certain
  period of their creation, currently ca. 75 years after the lifespan of
  the author) or with due consent from the respective authors.

I understand the PD part, but not the other part.  What does it mean?

They also have this:

  3.4  I have a suggestion.  Whom can I contact ?

  Feel free to send a mail to Dr. Kalyanasundaram . They will be glad
  to hear your suggestion or opinions, if any.

So maybe we should ask this person, assuming we want to include the
file in our benchmark.
