As of December, 27, 2013 ePubCrawler (http://www.rorohiko.com/epubcrawler) has ceased to be donation-ware. It has become ‘end-of-life’: it won’t be updated any more.
To replace it, we’re building the Crawler software. Crawler supersedes ePubCrawler. More info here:
The functionality of ePubCrawler will be covered by one of the Crawler personalities (FL-EPUB) that are under development still, and ePubCrawler will be replaced by the combo Crawler+FL-EPUB.
eCanCrusher (the free EPUB zip/unzipper) has been moved from the Rorohiko web site to this web site: http://www.DocDataFlow.com/eCanCrusher
