+# - Try to find C++ TR1 headers and libraries
+# Once done, this will define
+#
+#  TR1_USE_FILE, which you may "include" in your CMake file to be able
+#   to use TR1 features transparently
+#  TR1_INCLUDE_DIRS, any directories needed to access TR1 headers
+#  TR1_LIBRARY_DIRS, any directories needed to access (auto-link) TR1 libraries
+#  TR1_FOUND, If false, do not try to use TR1 features.
+#
+# If TR1 features are not built-in, we will try to use Boost to
+# substitute for them.
