I've been working on a plugin called "po", that adds support for multi-lingual wikis,
translated with gettext, using [po4a](http://po4a.alioth.debian.org/).

secondary parameter overriding the default locale (for messages like "N/A" as
percentage in po plugin). Alternatively (with above mentioned template support)
all such strings could be externalized as templates that can then be localized.

+# Robustness tests
+
+### Enabling/disabling the plugin
+
+* 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**
+
+### Changing the plugin config
+
+* 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)
+
+### Creating/deleting/renaming pages
+
+All cases of master/slave page creation/deletion/rename, both via RCS
+and via CGI, have been tested.
+
+### Misc
+
+* 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**

+Duplicate %links ?
+------------------
+
+I notice code in the scan hook that seems to assume
+that %links will accumulate duplicate links for a page.
+That used to be so, but the bug was fixed. Does this mean
+that po might be replacing the only link on a page, in error?
+--[[Joey]]

+> that is already there to `$links{$page}`. This other plugin's
+> effect might then be changed by po's `scan` hook... which could

+

+
+>>> Commit 3c2bffe21b91684 in my po branch does this. --[[intrigeri]]
