description="
A fast and light image viewer.

Feh is a fast, lightweight image viewer which uses imlib2.  It is
command line-driven and supports multiple images through slideshows,
thumbnail browsing or multiple windows, and montages or index prints 
(using TrueType fonts to display file info).  Advanced features include
fast dynamic zooming, progressive loading, loading via HTTP (with
reload support for watching webcams), recursive file opening (slideshow
of a directory hierarchy), and mouse wheel/keyboard control.
