GTK3-based button bar for wlroots-based compositors (program)

 nwg-bar is a GTK3-based button bar for wlroots-based compositors like sway,
 based on a user-defined JSON template and fully customizable using CSS.

 The nwg-bar command creates a button bar on the basis of a JSON template placed
 in the ~/.config/nwg-bar/ folder. By default the command displays a horizontal
 bar in the center of the screen. Use command line arguments to change the
 placement.

 This application is a part of the nwg-shell project.
