Thanks for the pointer, I didn't know such a beast existed.

I have a lot of large PDF files to be indexed, and pdftotext seems to be a
bit slow. I would hate to waste processor time converting the PDF to text
every time I want to update my search index.
So I created a script that searches my directories for PDF files, then
extracts the text into a .pdf.txt file (only if the .pdf.txt file does not
exist, or is older than the .pdf file). Thus I only have to extract the
text once, instead of every time I create the search index.
