qt6-webengine-dev-tools 6.4.2-final+dfsg-5 (arm64 binary) in ubuntu mantic

 Qt is a cross-platform C++ application framework. Qt's primary feature
 is its rich set of widgets that provide standard GUI functionality.
 .
 Qt WebEngine provides a Web browser engine that makes it easy to embed content
 from the World Wide Web into your Qt application.
 .
 This package contains the qwebengine_convert_dict tool which converts hunspell
 'dic' dictionaries to binary 'bdic' format, which is required by spellchecker
 in Qt 6 WebEngine. The package provides the convert-dict virtual package
 so that Hunspell dictionaries can depend on it at build time without having
 to adjust for future Qt releases.
 .
 Non-Qt packages using convert-bdic are not supported!
