Need script to automatically export Skim PDFs with embedded notes

I have a folder with a few thousand PDF files, most of which have Skim annotations (e.g., highlights and notes). If I had fewer files, I'd just go through each one, export the PDF with embedded notes, and be on my merry way, having the ability to read my annotations with Adobe Reader on a PC (this is the goal). But since there are so many files, I need a script that will automatically go through this folder, perform the "export as PDF with embedded notes" function for each PDF that has Skim annotations, and then give the new file the name of the original file plus "with skim notes" (or some other designation to indicate it's the version with embedded notes). Secondly, if I make further annotations to the original PDF, it'd be great if the script could update the exported file with the embedded notes. I assume this is possible, as it appears Skim has great applescript support, but I have no idea how to create one. Thank you so much for any help you can offer. WG
