+# Locate SDL_ttf library
+#
+# This module defines:
+#
+# ::
+#
+#   SDL2_TTF_LIBRARIES, the name of the library to link against
+#   SDL2_TTF_INCLUDE_DIRS, where to find the headers
+#   SDL2_TTF_FOUND, if false, do not try to link against
+#   SDL2_TTF_VERSION_STRING - human-readable string containing the version of SDL_ttf
+#
+#
+#
+# For backward compatibility the following variables are also set:
+#
+# ::
+#
+#   SDLTTF_LIBRARY (same value as SDL2_TTF_LIBRARIES)
+#   SDLTTF_INCLUDE_DIR (same value as SDL2_TTF_INCLUDE_DIRS)
+#   SDLTTF_FOUND (same value as SDL2_TTF_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).
