Hints

• asv-cid-contains-hyphen
  :4 - org.kde.kid3-qt
  The component ID contains a hyphen/minus. Using a hyphen is strongly discouraged, to improve interoperability with other tools such as D-Bus. A good option is to replace any hyphens with underscores (`_`).
• asv-summary-has-dot-suffix
  :61 - Editar metadatos de ficheiros de son.
  The component summary should not end with a dot (`.`).
• asv-unknown-tag
  :294 - developer
  Found invalid tag. Non-standard tags should be prefixed with `x-`. AppStream also provides the <custom/> tag to add arbitrary custom data to metainfo files. This tag is read by AppStream libraries and may be useful instead of defining new custom toplevel or `x-`-prefixed tags if you just want to add custom data to a metainfo file.
