/// <summary>
/// Represents a dynamically loaded unmanaged library in a (partially) platform independent manner.
- /// An important difference in library loading semantics is that on Windows, once we load a dynamic library using LoadLibrary,
- /// that library becomes instantly available for <c>DllImport</c> P/Invoke calls referring to the same library name.
- /// On Unix systems, dlopen has somewhat different semantics, so we need to use dlsym and <c>Marshal.GetDelegateForFunctionPointer</c>
- /// to obtain delegates to native methods.
+ /// First, the native library is loaded using dlopen (on Unix systems) or using LoadLibrary (on Windows).
+ /// dlsym or GetProcAddress are then used to obtain symbol addresses. <c>Marshal.GetDelegateForFunctionPointer</c>
+ /// transforms the addresses into delegates to native methods.
