rss2book release 19
Release 19 is done (get it in the Content subforum). It uses the iTextSharp library to generate PDF files without requiring htmldoc. The html to PDF conversion is fairly basic so you can still elect to use htmldoc if you want more sophisticated conversion (including TOC). This release can also generate RTF files with images.
I was hoping to have Gutenberg integration by now but haven't done so; nontheless I published a sample 'feed' which is an example of how you can use rss2book to format Project Gutenberg books for your e-Book device.
