worker binary package in Ubuntu Focal i386

 Worker is a file manager much like the Amiga's DirOpus. It can be
 controlled with mouse or keyboard. There is no restriction on the number
 or type of button functions. Files are recognized by both extension and
 content, content by recognizing common bytes in the sample files you show
 it. Drag & Drop is supported.
 .
 If xli or imagemagick is installed, it quickly previews pictures in the
 opposite pane. If x11-utils is installed, xmessage is used to display
 some informative messages.
