Access adobe digital editions from the command line

I'm looking to create a script for my 80-year old grandmother that downloads the books she needs, and converts them using the command-line version of Calibre, to kindle format so she can read them on her kindle. She gets a lot of her books from a service in the form of Adobe .epub books. AFAIK, none of these books have DRM on them prior to being converted, so let me be clear - I'm not asking how to strip DRM from an ebook.

What I am asking is whether there is a way to programmatically (from the command line is fine if Adobe Digital Editions supports CL args) use the ticket file to request a book from the library, and download it, in .epub form, to the local hard drive. I simply don't want my grandmother to have to go through all of the unneeded screens in Adobe开发者_C百科 Digital Editions' interface - she gets confused easily, and the interface tends to be overwhelming for her. I simply want to write a function (it can be a system() call to a command... that's fine) that will allow her to take a file received from the library or digital service and automatically retrieve the proper .epub file.

I have all of the other steps ready to go... I just can't find any way to retrieve the book from the service without using the DE interface.

Any suggestions?
