+Markup languages support
+------------------------
+
+Markdown is well supported. Some other markup languages supported by
+ikiwiki mostly work, but some pieces of syntax are not rendered
+correctly on the slave pages:
+
+* [[reStructuredText|rst]]: anonymous hyperlinks and internal
+  cross-references
+* [[wikitext]]: conversion of newlines to paragraphs
+* [[creole]]: verbatim text is wrapped, tables are broken
+* [[html]] and LaTeX: not supported yet; the dedicated po4a modules
+  could be used to support them, but they would need a security audit
+* other markup languages have not been tested.

-Page formats

-Markdown is well supported, great, but what about others?

-The [[po|plugins/po]] uses `Locale::Po4a::Text` for every page format;
-this can be expected to work out of the box with most other wiki-like
-formats supported by ikiwiki. Some of their ad-hoc syntax might be
-parsed in a strange way, but the worst problems I can imagine would be
-wrapping issues; e.g. there is code in po4a dedicated to prevent
-re-wrapping the underlined Markdown headers.

-While it would be easy to better support formats such as [[html]] or

-**TODO**: test the more popular formats and write proper documentation
