This application will display hOCR files using the OpenLibrary BookReader. To run it, you need Flask, lxml, wand and whoosh. Edit the BOOK_PATH variable in app.py to suit your environment and run the app with:

$ python app.py

You can now access the web interface on port 5000.

The directory with the books should have the following structure:

+<bookname>
    <bookname>.hocr
    +img
        0000.png
        0001.png
        ...

To generate an index with all of your books, direct a HTTP GET query to the /api/reindex endpoint.
