Hi everyone,
First of all, thanks for taking the time to read this and perhaps answer my questions, it's appreciated.

The Sony Reader PRS505 has just been released in the UK this month, and I've been thinking of picking one up, but...
Basically, I have a folder full of HTML files (in the thousands). There're all pretty consistently formatted because they're from the same few sites, so I'm prepared to take the time to write a "recipe" for them, and turn them all into nice LRF files. The problem is, I can't see how I can apply the recipe to them! I am actually considering manually creating an RSS XML file to feed the files to Calibre, but this will take me forever, and there must surely be a better way?
If there's a proper way to do this, I'll be very happy, because fooling Calibre with an ad-hoc RSS feed seems very clumsy, and basically not a good idea considering the amount of files I'm trying to format.

Perhaps I'm misunderstanding how this recipe feature works?
This issue is basically the deciding factor for whether or not I buy the reader, because my main reason for getting one is that I'm tired of reading fan fiction and original short stories on my computer screen, and so I really need to be able to find a way to quickly and easily process them.
