+PUGL
+====
+
+Pugl is a minimal portable API for GUIs which supports embedding and is
+suitable for use in plugins.  It works on X11, Mac OS X, and Windows.  GUIs can
+be drawn with OpenGL or Cairo.
+
+Pugl is vaguely similar to GLUT, but with some significant distinctions:
+
+ * Minimal in scope, providing only what is necessary to draw and receive
+   keyboard and mouse input.
+
+ * No reliance on static data whatsoever, so the API can be used in plugins or
+   multiple independent parts of a program.
+
+ * Single implementation, which is small, liberally licensed Free / Open Source
+   Software, and suitable for direct inclusion in programs if avoiding a
+   library dependency is desired.
+
+ * Support for embedding in other windows, so Pugl code can draw to a widget
+   inside a larger GUI.
+
+ * More complete support for keyboard input, including additional "special"
+   keys, modifiers, and support for detecting individual modifier key presses.
+
+For more information, see <http://drobilla.net/software/pugl>.
