+*
+* rcore_drm - Functions to manage window, graphics device and inputs
+*
+* PLATFORM: DRM
+* - Raspberry Pi 0-5 (DRM/KMS)
+* - Linux DRM subsystem (KMS mode)
+*
+* LIMITATIONS:
+* - Most of the window/monitor functions are not implemented (not required)
+*
+* POSSIBLE IMPROVEMENTS:
+* - Improvement 01
+* - Improvement 02
+*
+* ADDITIONAL NOTES:
+* - TRACELOG() function is located in raylib [utils] module
+*
+* CONFIGURATION:
+* #define SUPPORT_SSH_KEYBOARD_RPI (Raspberry Pi only)
+* Reconfigure standard input to receive key inputs, works with SSH connection.
+* WARNING: Reconfiguring standard input could lead to undesired effects, like breaking other
+* running processes orblocking the device if not restored properly. Use with care.
+*
+* DEPENDENCIES:
+* - DRM and GLM: System libraries for display initialization and configuration
+* - gestures: Gestures system for touch-ready devices (or simulated from mouse inputs)

+* rcore_web - Functions to manage window, graphics device and inputs
+*
+* PLATFORM: WEB
+* - HTML5 (WebAssembly)
+*
+* LIMITATIONS:
+* - Limitation 01
+* - Limitation 02
+*
+* POSSIBLE IMPROVEMENTS:
+* - Replace glfw3 dependency by direct browser API calls (same as library_glfw3.js)
+*
+* ADDITIONAL NOTES:
+* - TRACELOG() function is located in raylib [utils] module
+*
+* CONFIGURATION:
+* #define RCORE_PLATFORM_CUSTOM_FLAG
+* Custom flag for rcore on target platform -not used-
+*
+* DEPENDENCIES:
+* - emscripten: Allow interaction between browser API and C
+* - gestures: Gestures system for touch-ready devices (or simulated from mouse inputs)
