I agree. This has already been covered by others, but HTML consists of multiple files, and so is not convenient to store or transmit atomically. Also, HTML is often difficult to print (you have to explicitly remove the page decorations added by the site (or find the 'print' option on the page). > For documentation of the U-Boot boot loader we use a very different > approach: documentation is created, stored and edited in a wiki > (using FosWiki, see http://foswiki.org/).

This is really interesting. Several years ago, CELF tried to add a similar capability to MoinMoin (the ability to take arbitrary page lists, and automatically publish them to PDF). Unfortunately, it didn't work very well. The tools to produce PDF were pretty bad back then. I think the wiki approach is very good for collecting the information, and having a way to snapshot and publish the items solves some of the problems wikis have (uneven editing across multiple pages over time can lead to inconsistent pages). It sounds like the tools have improved since we did this, and maybe we should look again and see if there's something similar we could add to the elinux wiki. -- Tim ============================= Tim Bird Architecture Group Chair, CE Workgroup of the Linux Foundation Senior Staff Engineer, Sony Network Entertainment ============================= -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
