+///
+/// \file
+/// \brief This file implements the C++11 feature migration tool main function
+/// and transformation framework.
+///
+/// Usage:
+/// cpp11-migrate [-p <build-path>] <file1> <file2> ... [-- [compiler-options]]
+///
+/// Where <build-path> is a CMake build directory containing a file named
+/// compile_commands.json which provides compiler options for building each
+/// sourc file. If <build-path> is not provided the compile_commands.json file
+/// is searched for through all parent directories.
+///
+/// Alternatively, one can provide compile options to be applied to every source
+/// file after the optional '--'.
+///
+/// <file1>... specify the paths of files in the CMake source tree, with the
+/// same requirements as other tools built on LibTooling.
+///
