-===================================
-# 0: General Information
-===================================
-
-- **Programming Language**: C / C++
-- **Build System**: Make / NeBuild 
-- **Purpose**: System Call Interface (SCI) for NeKernel
-
-===================================
-# 1: How It Works
-===================================
-
-- This header provides the raw API surface for accessing NeKernel's system calls.
-
-- It is **not** directly used by applications.
-    - Instead, it is abstracted by the **SystemSDK**, which presents a stable, high-level interface.
-
-- At runtime:
-    - System calls are routed from user-space code to the **kernel syscall manager**.
-    - The syscall manager executes the requested operation and returns control to `libSystem`.
-    - Finally, the result is delivered back to the originating process.
-
-- This separation ensures that:
-    - The SCI remains low-level and close to the ABI.
-    - `SystemSDK` provides portability and shielding from changes in syscall internals.
