Hints

• asv-desktop-app-launchable-omitted
  org.kde.kwave.appdata.xml -
  This `desktop-application` component has no `desktop-id` launchable tag, however it contains all the necessary information to display the application. The omission of the launchable entry means that the application can not be launched directly from installers or software centers. If this is intended, this information can be ignored, otherwise it is strongly recommended to add a launchable tag as well.
• asv-url-not-secure
  org.kde.kwave.appdata.xml:143 - http://kwave.sourceforge.net/
  Consider using a secure (HTTPS) URL for this web link.
• asv-summary-has-dot-suffix
  org.kde.kwave.appdata.xml:59 - Kwave er eit lydredigeringsprogram bygd på KDE Frameworks 5.
  The component summary should not end with a dot (`.`).
• asv-content-rating-missing
  org.kde.kwave.appdata.xml -
  This component has no `content_rating` tag to provide age rating information. You can generate the tag data online by answering a few questions at https://hughsie.github.io/oars/
