+If you don't want to use a branch of ikiwiki, manual installation requires
+these files (use the "raw" link in gitweb to download):
+
+* [trail.pm](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/blob/trail3:/IkiWiki/Plugin/trail.pm)
+ in an `IkiWiki/Plugin` subdirectory of your configured `plugindir`
+* [page.tmpl](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/blob/trail3:/templates/page.tmpl)
+ and
+ [trails.tmpl](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/blob/trail3:/templates/trails.tmpl)
+ in your configured `templatedir`, or a `templates` subdirectory of your wiki repository
+* the trail-related bits from the end of the
+ [stylesheet](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/blob/trail3:/doc/style.css)
+ (put them in your local.css)
+* the trail-related bits at the end of the
+ [actiontabs](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/blob/trail3:/themes/actiontabs/style.css)
+ or [blueview/goldtype](http://git.pseudorandom.co.uk/smcv/ikiwiki.git/blob/trail3:/themes/blueview/style.css)
+ stylesheets, if you use one of those themes (again, put them in your local.css)
+
+The branch also includes [[todo/test_coverage]] machinery.
+
+Demo:
+
+* [in use on entries in my blog](http://smcv.pseudorandom.co.uk/)
+* [a demo trail based on links](http://demo.hosted.pseudorandom.co.uk/trail/)
+* [a demo hybrid trail/inline](http://demo.hosted.pseudorandom.co.uk/trail2/)
+
+The page `e` is in both demo trails, to demonstrate how a page in more than
+one trail looks.
+
+The `smcv/trail2` branch is an older version of `trail3` which used typed links
+as its data structure, resulting in timing-related limitations (it couldn't
+select pages for the trail by using pagespecs, because pagespecs can't be
+evaluated correctly until the scan stage has finished).
+
+Updated, November 2011:
+
+* reinstated `inline` integration ([[report]] integration would probably be
+ pretty easy too, if this gets merged)
+* switched from typed links back to a custom data structure to avoid
+ chicken/egg problems with ordering
+* create typed links too, as a side-effect, but not when using an inline
+* regression test with nearly full coverage
+* CSS for the default anti-theme and all built-in themes (it looks nicest
+ in the default anti-theme and in actiontabs - the demo uses actiontabs)
+
+Known bugs:
+
+* the blueview and goldtype CSS nearly work, but the alignment is a bit off
