+# - Find SDL2_net library and headers
+# 
+# Find module for SDL_net 2.0 (http://www.libsdl.org/projects/SDL_net/).
+# It defines the following variables:
+#  SDL2_NET_INCLUDE_DIRS - The location of the headers, e.g., SDL_net.h.
+#  SDL2_NET_LIBRARIES - The libraries to link against to use SDL2_net.
+#  SDL2_NET_FOUND - If false, do not try to use SDL2_net.
+#  SDL2_NET_VERSION_STRING
+#    Human-readable string containing the version of SDL2_net.
+#
+# Also defined, but not for general use are:
+#   SDL2_NET_INCLUDE_DIR - The directory that contains SDL_net.h.
+#   SDL2_NET_LIBRARY - The location of the SDL2_net library.
