+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.
+
+Security
+========
+
+[[./security]] contains a detailed security analysis of this plugin
+and its dependencies.
+
+When using po4a older than 0.35, it is recommended to uninstall
+`Text::WrapI18N` (Debian package `libtext-wrapi18n-perl`), in order to
+avoid a potential denial of service.

-Misc. improvements
-------------------
+Robustness tests
+----------------

 
 

-### page titles
+### Enabling/disabling the plugin

 
 

-Use nice page titles from meta plugin in links, as inline already
-does. This is actually a duplicate for
-[[bugs/pagetitle_function_does_not_respect_meta_titles]], which might
-be fixed by something like [[todo/using_meta_titles_for_parentlinks]].
+* enabling the plugin with `po_translatable_pages` set to blacklist: **OK**
+* enabling the plugin with `po_translatable_pages` set to whitelist: **OK**
+* enabling the plugin without `po_translatable_pages` set: **OK**
+* disabling the plugin: **OK**

 
 

-### backlinks
+### Changing the plugin config

 
 

-`po_link_to = negotiated`: if a given translatable `sourcepage.mdwn`
-links to \[[destpage]], `sourcepage.LL.po` also link to \[[destpage]],
-and the latter has the master page *and* all its translations listed
-in the backlinks.
+* adding existing pages to `po_translatable_pages`: **OK**
+* removing existing pages from `po_translatable_pages`: **OK**
+* adding a language to `po_slave_languages`: **OK**
+* removing a language from `po_slave_languages`: **OK**
+* changing `po_master_language`: **OK**
+* replacing `po_master_language` with a language previously part of
+  `po_slave_languages`: needs two rebuilds, but **OK** (this is quite
+  a perverse test actually)

 
 

-`po_link_to = current`: seems to work nicely
+### Creating/deleting/renaming pages

 
 

-### parentlinks
+All cases of master/slave page creation/deletion/rename, both via RCS
+and via CGI, have been tested.

 
 

-When `usedirs` is disabled and the home page is translatable, the
-parent link to the wiki home page is broken (`/index.html`).
+### Misc

 
 

-Translation quality assurance
------------------------------
+* general test with `usedirs` disabled: **OK**
+* general test with `indexpages` enabled: **not OK**
+* general test with `po_link_to=default` with `userdirs` enabled: **OK**
+* general test with `po_link_to=default` with `userdirs` disabled: **OK**

 
 

-Modifying a PO file via the CGI must be forbidden if the new version
-is not a valid PO file. As a bonus, check that it provides a more
-complete translation than the existing one.
+Misc. bugs
+----------

 
 

-A new `cansave` type of hook would be needed to implement this.
+Documentation
+-------------

 
 

-Note: committing to the underlying repository is a way to bypass
-this check.
+Maybe write separate documentation depending on the people it targets:
+translators, wiki administrators, hackers. This plugin may be complex
+enough to deserve this.
