Usage Tip
You can speed Textcavator up by processing a directory of PDFs into text files with pdftotext and pointing Textcavator to the text files. This also works well for proprietary files (like InDesign) that have their own export to text option.
If you have mixed file types in a directory, though, adding a text conversion will only cause Textcavator to read the original and the conversion both.
And then, of course, you can add that directory to A Few Favorites Macro to zip over there and run Textcavator on it.
