export [--language LANGUAGE] [--prefix [PREFIX]]

Exporting after adding flags and places for Norway/Østfeldt/[all municipalities]/[some villages] using tools/wiki-place and tools/wiki-flag.

File already exists at path: places/flags/.png

Empty filename?

Does the flag's placename exist as a feature in the parent data.geojson file?

[Amgine0]

These three issues were all from a single run of export. The immediately previous output was a PHP Notice for undefined index for Våler, which does have a placename as a feature in the parent data.geojson, and Våler's data.geojson has a placename feature for Kirkebygden (which does not yet have a flag/coat of arms)

But I have a suspicion: would the Scilly Isles .svg happen to have an embedded png in it?
