With Quirky, at first bootup, QuickSetup displays, followed by 'welcome1stboot'. The latter is a window with some introductory information, such as about the desktop icons and tray applets, and links to further help.
In woof-CE, that welcome1stboot is a web page, in Quirky it is a binary executable (written in BaCon).
For Easy, I have created /usr/share/doc/easy/welcome.htm, and this now replaces welcome1stboot.
As easy has the lovely new HelpSurfer html viewer enhanced by SFR, this is used to view welcome.htm
Technical note: welcome.htm is launched from /usr/sbin/delayedrun, which in turn is launched from /root/.xinitrc when X starts up.
I used Google Translate to create welcome_de.htm, etc.. After the user has chosen a language in QuickSetup, delayedrun will look for a matching welcome_*.htm and if exists will launch it.
