Release day classic! Fixed two bugs not noticed until just after release. One was a crash in the markdown parser which ironically broke the 0.2 release announcement.
Pushed an emergency fix, will resolve with a better fix in time.
Also trying out committing release numbers to the in tree version string.
The way the help files are displayed has changed slightly, better integration with the site, but the html files have always been in viewdir/docs.
The datadir is for user data, of course, but specifically anything expected to be preserved between releases, like datadir/views/local.css. The viewdir is expected to be tied to the release and be replaced, which includes help files.
