+# FindWinSock
+# --------
+#
+# Find the native realtime includes and library.
+#
+# IMPORTED Targets
+# ^^^^^^^^^^^^^^^^
+#
+# This module defines :prop_tgt:`IMPORTED` target ``WINSOCK::WINSOCK``, if
+# WINSOCK has been found.
+#
+# Result Variables
+# ^^^^^^^^^^^^^^^^
+#
+# This module defines the following variables:
+#
+# ::
+#
+#   WINSOCK_INCLUDE_DIRS  - where to find winsock.h, etc.
+#   WINSOCK_LIBRARIES     - List of libraries when using librt.
+#   WINSOCK_FOUND         - True if realtime library found.
+#
+# Hints
+# ^^^^^
+#
+# A user may set ``WINSOCK_ROOT`` to a realtime installation root to tell this
+# module where to look.
