Are there text versions of the Clinton Emails?

The State Department released 7,000 of the Clinton emails the other day.

Sadly, they've posted PDFs of printed copies of the email.

Are there text versions available? I thought it would be interesting to play with them, doing simple term frequency, map out relationships, etc.
