FreeTube is a YouTube client.

This script builds a Slackware package using the official binary.
The download is an AppImage which is placed in /opt
however source is also available on github.

NOTE: THERE HAS BEEN A SIGNIFICANT CHANGE IN THE FREETUBE FEATURE
SET AS OF v0.24.0 Beta. As stated by the developers, "The built-in
download feature has been removed. This functionality was already
partially broken and became completely unusable following the
introduction of SABR. In its existing state, it lacked many features
users typically expect from a YouTube downloader, and restoring it
would have required a significant rewrite just to bring it back to a
minimal, maintenance-level condition. Given the scope of work required
and the availability of more robust, dedicated tools such as yt-dlp
and various online download services, we determined that removing the
built-in downloader was the most practical decision." (See version
