+Language display order
+----------------------
+
+Jonas pointed out that one might want to control the order that links to
+other languages are listed, for various reasons. Currently, there is no
+order, as `po_slave_languages` is a hash. It would need to be converted
+to an array to support this. (If twere done, twere best done quickly.)

+po files in underlay
+--------------------
+
+I think this plugin doesn't yet allow po files to be present in an
+underlay to translate files also from the underlay.
+
+In `istranslatablefile`, it specifically checks that
+the file is present in srcdir.
+
+Problem with this is that it precludes using po to translate
+the basewiki (work which is well under way for Danish BTW),
+since the translated po files cannot really be used.
+
+A further problem comes if one wants to use a non-English language as the
+`po_master_language`. It would be good to get a translated
+basewiki, taking po files from the underlay and using them as the primary
+page sources, but this plugin doesn't yet support that.
+
+And, maybe it shouldn't? A user would not expect to see a po file when
+editing the index page of their wiki, just because they're using a
+different language. Instead, we might want to build localized .mdwn files
+for the basewiki, and then ikiwiki would just use that translated underlay.
+The when the user edits index, they get a nice mdwn file to start from.
+
+So, we seem to have two cases, in one po files from the underlay should be
+used, in the other not. Hmm. Support both?
+
+> Update -- I've written po2wiki, which can spit out translated underlays
+> in markdown format, and made the po plugin enable use of such underlays
+> when the master language is not `en`.

+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?
