+    sokol_spine.h -- a sokol-gfx renderer for the spine-c runtime
+                     (see https://github.com/EsotericSoftware/spine-runtimes/tree/4.1/spine-c)
+
+    Project URL: https://github.com/floooh/sokol
+
+    Do this:
+        #define SOKOL_IMPL or
+        #define SOKOL_SPINE_IMPL
+
+    before you include this file in *one* C or C++ file to create the
+    implementation.
+
+    The following defines are used by the implementation to select the
+    platform-specific embedded shader code (these are the same defines as
+    used by sokol_gfx.h and sokol_app.h):
+
+    SOKOL_GLCORE33
+    SOKOL_GLES2
+    SOKOL_GLES3
+    SOKOL_D3D11
+    SOKOL_METAL
+
+    ...optionally provide the following macros to override defaults:
+
+    SOKOL_ASSERT(c)     - your own assert macro (default: assert(c))
+    SOKOL_SPINE_API_DECL    - public function declaration prefix (default: extern)
+    SOKOL_API_DECL      - same as SOKOL_SPINE_API_DECL
+    SOKOL_API_IMPL      - public function implementation prefix (default: -)
+    SOKOL_LOG(msg)      - your own logging function (default: puts(msg))
+    SOKOL_UNREACHABLE() - a guard macro for unreachable code (default: assert(false))
+
+    If sokol_spine.h is compiled as a DLL, define the following before
+    including the declaration or implementation:
+
+    SOKOL_DLL
+
+    On Windows, SOKOL_DLL will define SOKOL_SPINE_API_DECL as __declspec(dllexport)
+    or __declspec(dllimport) as needed.
+
+    Include the following headers before including sokol_spine.h:
+
+        sokol_gfx.h
+
+    Include the following headers before include the sokol_spine.h *IMPLEMENTATION*:
+
+        spine/spine.h
