+### `%typedlinks`
+
+The `%typedlinks` hash records links of specific types. Do not modify this
+hash directly; call `add_link()`. The keys are page names, and the values
+are hash references. In each page's hash reference, the keys are link types
+defined by plugins, and the values are hash references with link targets
+as keys, and 1 as a dummy value, something like this:
+
+ $typedlinks{"foo"} = {
+ tag => { short_word => 1, metasyntactic_variable => 1 },
+ next_page => { bar => 1 },
+ };
+
+Ordinary [[WikiLinks|ikiwiki/WikiLink]] appear in `%links`, but not in
+`%typedlinks`.
+
### `%pagesources`
The `%pagesources` has can be used to look up the source filename
filename of the page. For example, `targetpage("foo", "rss", "feed")`
will yield something like `foo/feed.rss`.
-### `add_link($$)`
+### `add_link($$;$)`
This adds a link to `%links`, ensuring that duplicate links are not
added. Pass it the page that contains the link, and the link text.
+An optional third parameter sets the link type. If not specified,
+it is an ordinary [[ikiwiki/WikiLink]].
+
## Miscellaneous
### Internal use pages
they match; "created_before(foo)" is influenced by the metadata of foo;
while "glob(*)" is not influenced by the contents of any page.
+ ### Sorting plugins
+
+ Similarly, it's possible to write plugins that add new functions as
+ [[ikiwiki/pagespec/sorting]] methods. To achieve this, add a function to
+ the IkiWiki::SortSpec package named `cmp_foo`, which will be used when sorting
+ by `foo` or `foo(...)` is requested.
+
+ The names of pages to be compared are in the global variables `$a` and `$b`
+ in the IkiWiki::SortSpec package. The function should return the same thing
+ as Perl's `cmp` and `<=>` operators: negative if `$a` is less than `$b`,
+ positive if `$a` is greater, or zero if they are considered equal. It may
+ also raise an error using `error`, for instance if it needs a parameter but
+ one isn't provided.
+
+ The function will also be passed one or more parameters. The first is
+ `undef` if invoked as `foo`, or the parameter `"bar"` if invoked as `foo(bar)`;
+ it may also be passed additional, named parameters.
+
### Setup plugins
The ikiwiki setup file is loaded using a pluggable mechanism. If you look
