QNapi is a Qt-based subtitle downloader for movie files. It can search
several subtitle databases, including NapiProjekt, OpenSubtitles, and
Napisy24, and provides both GUI and command-line modes.

QNapi needs 7z or 7za at runtime to unpack downloaded subtitles.
SlackBuilds.org includes p7zip; if QNapi does not detect it
automatically, set the 7zip path in QNapi's preferences.

The OpenSubtitles.org API used by old applications has been deprecated,
so some providers may work better than others. Test real subtitle
downloads after installation, especially if you depend on a
specific provider.
