Crawler is a generic document processor engine. It can be used for document conversion, as well as reporting and statistics.
Crawler is work-in-progress. The first release works with Adobe InDesign CS5 Server (or Adobe InDesign CS5) or higher as the source format. Future versions will support additional source formats.
This Wiki is currently under construction, and it changes/grows day by day.
Crawler was developed from scratch, but it is based on a range of ideas that emerged during the development of the ePubCrawler software (http://www.rorohiko.com/epubcrawler).
ePubCrawler won't be developed further. At some point in time, Crawler will supersede ePubCrawler, and EPUB will simply be one of the target formats supported by Crawler.
