The Emacs manuals are very detailed, but this is also an issue: it may be difficult for the user to distinguish between details and important things (in particular, when they are unintuitive, as for behavior different from standards and other applications). The wiki is a good example: even experts (who contributed to the wiki) can be wrong or give bad advice. So when there is something misleading, the manual should give big warnings and make sure that the user will see them. Also note that regexps are used everywhere, in many applications, and users should not be expected to read again and again *whole* parts of the manuals about common things like regexps. -- Vincent Lefèvre - Web: 100% accessible validated (X)HTML - Blog: Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
