+    sokol_glue.h -- glue helper functions for sokol headers
+
+    Project URL: https://github.com/floooh/sokol
+
+    Do this:
+        #define SOKOL_IMPL or
+        #define SOKOL_GLUE_IMPL
+    before you include this file in *one* C or C++ file to create the
+    implementation.
+
+    ...optionally provide the following macros to override defaults:
+
+    SOKOL_ASSERT(c)     - your own assert macro (default: assert(c))
+    SOKOL_GLUE_API_DECL - public function declaration prefix (default: extern)
+    SOKOL_API_DECL      - same as SOKOL_GLUE_API_DECL
+    SOKOL_API_IMPL      - public function implementation prefix (default: -)
+
+    If sokol_glue.h is compiled as a DLL, define the following before
+    including the declaration or implementation:
+
+    SOKOL_DLL
+
+    On Windows, SOKOL_DLL will define SOKOL_GLUE_API_DECL as __declspec(dllexport)
+    or __declspec(dllimport) as needed.
+
+    OVERVIEW
+    ========
+    sokol_glue.h provides glue helper functions between sokol_gfx.h and sokol_app.h,
+    so that sokol_gfx.h doesn't need to depend on sokol_app.h but can be
+    used with different window system glue libraries.
+
+    PROVIDED FUNCTIONS
+    ==================
+
+    sg_environment sglue_environment(void)
+
+        Returns an sg_environment struct initialized by calling sokol_app.h
+        functions. Use this in the sg_setup() call like this:
+
+        sg_setup(&(sg_desc){
+            .environment = sglue_environment(),
+            ...
+        });
+
+    sg_swapchain sglue_swapchain(void)
+
+        Returns an sg_swapchain struct initialized by calling sokol_app.h
+        functions. Use this in sg_begin_pass() for a 'swapchain pass' like
+        this:
+
+        sg_begin_pass(&(sg_pass){ .swapchain = sglue_swapchain(), ... });
