In case they are of use to anyone, here are links I've collected over 
the years (some may be dead) to other tools that include the capability 
to extract text from a vector PDF (not a raster one that still needs to 
be OCRd):

* pdfx: http://pdfx.cs.man.ac.uk/

* LA-PDFText: https://code.google.com/p/lapdftext/

* pdf2htmlEX: https://github.com/coolwanglu/pdf2htmlEX

* Apache PDFBox: http://pdfbox.apache.org/

* pdf2txt.py, part of PDFMiner: 
http://www.unixuser.org/~euske/python/pdfminer/

* pdftotext (part of xpdf)

See also the list at http://scholrev.org/hackathon/ and this discussion 
of using Jade, Gemini, and Adobe Acrobat to extract text from a PDF:
