Phoenix from the Flames: ATL Docs

We have a new strategy for ATL documentation: it was sometimes hard to find an up-to-date and complete version of ATL docs... Now all informations have been merged into the ATL wiki, on three main pages:- http://wiki.eclipse.org/ATL/Concepts- http://wiki.eclipse.org/ATL/User_Guide- http://wiki.eclipse.org/ATL/Developer_GuideThose page will also be available offline, into the eclipse.help ATL doc plugin (available into ATL SDK builds), thanks to WikiText: this great tool provides a very stable way to convert wiki pages into eclipse.help html pages.So users (and contributors) are now allowed to modify, update ATL documentation: then relevant corrections will be simply applied on each new ATL build, using WikiText !
