+# - Returns a version string from Git
+#
+# These functions force a re-configure on each git commit so that you can
+# trust the values of the variables in your build system.
+#
+#  get_git_head_revision(<refspecvar> <hashvar> [<additional arguments to git describe> ...])
+#
+# Returns the refspec and sha hash of the current head revision
+#
+#  git_describe(<var> [<additional arguments to git describe> ...])
+#
+# Returns the results of git describe on the source tree, and adjusting
+# the output so that it tests false if an error occurs.
+#
+#  git_get_exact_tag(<var> [<additional arguments to git describe> ...])
+#
+# Returns the results of git describe --exact-match on the source tree,
+# and adjusting the output so that it tests false if there was no exact
+# matching tag.
+#
+# Requires CMake 2.6 or newer (uses the 'function' command)
