+
+    Do this:
+        #define SOKOL_CLAY_IMPL
+
+    before you include this file in *one* C file to create the
+    implementation.
+
+    Optionally provide the following configuration define both before including the
+    the declaration and implementation:
+
+    SOKOL_CLAY_NO_SOKOL_APP    - don't depend on sokol_app.h (see below for details)
+
+    Include the following headers before sokol_clay.h (both before including
+    the declaration and implementation):
+
+        sokol_gl.h
+        sokol_fontstash.h
+        sokol_app.h         (except SOKOL_CLAY_NO_SOKOL_APP)
+        clay.h
+
+    FEATURE OVERVIEW:
+    =================
+    sokol_clay.h implements the rendering and event-handling code for Clay
+    (https://github.com/nicbarker/clay) on top of sokol_gl.h and (optionally)
+    sokol_app.h.
+
+    Since sokol_fontstash.h already depends on sokol_gl.h, the rendering is
+    implemented using sokol_gl calls. (TODO: make fontstash optional?)
+
+    The sokol_app.h dependency is optional and used for input event handling.
+    If you only use sokol_gfx.h but not sokol_app.h in your application,
+    define SOKOL_CLAY_NO_SOKOL_APP before including the implementation
+    of sokol_clay.h, this will remove any dependency to sokol_app.h, but
+    you must call sclay_set_layout_dimensions and handle input yourself.
+
+    sokol_clay.h is not thread-safe, all calls must be made from the
+    same thread where sokol_gfx.h is running.
+
+    HOWTO:
+    ======
+
+    --- To initialize sokol-clay, call sclay_setup(). This can be done
+        before or after Clay_Initialize.
+
+    --- Create an array of sclay_font_t and fill it by calling one of:
+
+            sclay_font_t sclay_add_font(const char *filename);
+            sclay_font_t sclay_add_font_mem(unsigned char *data, int dataLen);
+
+        The fontId value in Clay corresponds to indices in this array. After calling
+        Clay_Initialize but before calling any layout code, do this:
+
+            Clay_SetMeasureTextFunction(sclay_measure_text, &fonts);
+
+        where `fonts` is the abovementioned array.
+
+    --- At the start of a frame, call sclay_new_frame() if you're using sokol_app.h.
+        If you're not using sokol_app.h, call:
+ 
+            void sclay_set_layout_dimensions(Clay_Dimensions size, float dpi_scale);
+
+        at the start of the frame (or just when the window is resized.)
+
+        Either way, do some layout, then at the end of the frame call sclay_render:
+
+            sg_begin_pass(...)
+            // other rendering...
+            sclay_render(renderCommands, &fonts);
+            // other rendering...
+            sgl_draw();
+            sg_end_pass();
+            sg_commit();
+
+        One caveat: sclay_render assumes the default gl view matrix, and handles scaling
+        automatically. If you've adjusted the view matrix, remember to first call:
+
+            sgl_matrix_mode_modelview();
+            sgl_load_identity();
+
+        before calling sclay_render.
+
+    --- if you're using sokol_app.h, from inside the sokol_app.h event callback,
+        call:
+
+            void sclay_handle_event(const sapp_event* ev);
+
+        Unfortunately Clay does not currently provide feedback on whether a mouse
+        click was handled or not.
+
+    --- finally, on application shutdown, call
+
+            sclay_shutdown()
