I know this is probably a dumb question, but why do I need to validate using epub preflight as well as epubcheck?

And at the moment I'm using pdurrant's wonderful epubcheck droplet (http://www.mobileread.com/forums/showthread.php?t=55576). Is there anything similar for epub preflight? I break out in hives whenever I use Terminal.

Also, though - when I download "preflight" from this page (http://code.google.com/p/epubcheck/downloads/list), the readme talks about epubcheck and not preflight. Am I missing something? Is preflight already rolled into the latest version of epubcheck?

Actually, using FlightCrew is easier then ePubCheck as you get error messages that are more in English then geek.

As for preflight, never heard of it.

I find epubcheck's information to be pretty useful. Maybe that makes me a geek? (Ha ha.)

But I'm concerned with preflight because the iBookstore publisher guide suggests validating via the Threepress site (http://www.threepress.org/document/epub-validate/), and Threepress mentions epubpreflight on their validation page.

I'll do a little more digging, I guess.

Why are you concerned with an obsolete ePub validator from 2008 that no longer really exists? I believe that epubpreflight became ePubCheck. Also, the problem is that some of the way you code eBooks for iBooks isn't going to validate.
