Create a method for converting an RTF file into a Keynote presentation

I need a repeatable method of automatically converting a text document into a Keynote presentation. Each paragraph in the file should be converted into a new slide, followed by a blank slide. Also, these text files will contain Hebrew text, which will need to be imported into Keynote intact. Finally, the keynote presentation needs to be formatted a certain way, with 1-2 lines of text at the bottom of each slide, white on a black background. ## Deliverables This will be used to screen subtitles onto a movie screen. The idea is to sit in the movie theater and advance the subtitles manually in sync with the film. Some subtitles are one title long and some are two, so the thing to look for is a double line break. Each subtitle needs to be at the bottom of the slide, and followed by a blank, black slide, and the text must be identical to the original text file. Keynote seems to screw Hebrew up, so this might pose a problem. In my tests, PowerPoint actually handled the Hebrew very well. If unachievable in Keynote, I'm willing to consider a PowerPoint-based solution, but I'd much rather stay Microsoft-free.
