+Generates AppStream metainfo for a set of Progressive Web Apps
+
+Usage: pwa-metainfo-generator.py LIST.CSV
+
+The CSV format expected looks like this:
+
+https://app.diagrams.net/,Apache-2.0
+https://pinafore.social/,AGPL-3.0-only
+...
+
+The output will be written to a file with the same name as the input but a .xml
+file ending.
+
+This tool uses the web app's manifest to fill out the AppStream info, so an
+Internet connection is required
