+# - Locate SDL2_net library
+# This module defines:
+# SDL2_NET_LIBRARIES, the name of the library to link against
+# SDL2_NET_INCLUDE_DIRS, where to find the headers
+# SDL2_NET_FOUND, if false, do not try to link against
+# SDL2_NET_VERSION_STRING - human-readable string containing the version of SDL2_net
+#
+# For backward compatiblity the following variables are also set:
+# SDLNET_LIBRARY (same value as SDL2_NET_LIBRARIES)
+# SDLNET_INCLUDE_DIR (same value as SDL2_NET_INCLUDE_DIRS)
+# SDLNET_FOUND (same value as SDL2_NET_FOUND)
+#
+# $SDLDIR is an environment variable that would
+# correspond to the ./configure --prefix=$SDLDIR
+# used in building SDL.
+#
+# Created by Eric Wing. This was influenced by the FindSDL.cmake
+# module, but with modifications to recognize OS X frameworks and
+# additional Unix paths (FreeBSD, etc).
