I haven't tried them.) That is, render every `foo.type` for the rendered types (mdwn etc.) as `foo/index.html`, generating links to `foo/` instead of `foo.html`, but not earlier than the point where the .html as presently appended to the page name. Then you just flip a build time option on an existing wiki without any changes to that, and the pages appear elsewhere. The `index.type` files might be left out of this scheme, though (and the top-level one, of course, has to). --[[tuomov]] - -> Well, get around to wasting time on it after all, and [here's the patch](http://iki.fi/tuomov/use_dirs.diff). The `-use_dirs` option will cause everything to be rendered inside directories. There may still be some problems with it, that need looking into (it doesn't e.g. check for conflicts between foo/index.mdwn and foo.mdwn), but seems to work well enough for me... The patch also improves, I think, the parentlinks code a little, as it uses generic routines to actually find the target location now. The only places where the `use_dirs` option is used is `htmlpage`, in fact, although other specific kludges needed to be removed from other points in the code. - ->> FWIW, [use_dirs.diff](http://iki.fi/tuomov/use_dirs.diff) applies cleanly, and works well for me.
