+gtk-layer-shell is a library to write GTK applications that
+use Layer Shell.
+Layer Shell is a Wayland protocol for desktop shell components,
+such as panels, notifications and wallpapers. You can use it to anchor
+your windows to a corner or edge of the output, or stretch them across
+the entire output. It supports all Layer Shell features including popups
+and popovers (GTK popups Just Work™). This Library is compatible with
+C, C++ and any language that supports GObject introspection files
+(Python, Vala, etc,).
+
+This library only works on Wayland, and only on Wayland compositors
+that support the Layer Shell protcol. Layer shell is supported on:
+
+•wlroots based compositors (such as Sway)
+•Mir-based compositors (some may not enable the protocol by default
+and require --add-wayland-extension zwlr_layer_shell_v1)
+
+Layer shell is not supported on:
+
+•Gnome-on-Wayland
+•Any X11 desktop

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
