+//===----------------------------------------------------------------------===//
+//
+//  This file implements a clang-check tool that runs the
+//  clang::SyntaxOnlyAction over a number of translation units.
+//
+//  Usage:
+//  clang-check <cmake-output-dir> <file1> <file2> ...
+//
+//  Where <cmake-output-dir> is a CMake build directory in which a file named
+//  compile_commands.json exists (enable -DCMAKE_EXPORT_COMPILE_COMMANDS in
+//  CMake to get this output).
+//
+//  <file1> ... specify the paths of files in the CMake source tree. This  path
+//  is looked up in the compile command database. If the path of a file is
+//  absolute, it needs to point into CMake's source tree. If the path is
+//  relative, the current working directory needs to be in the CMake source
+//  tree and the file must be in a subdirectory of the current working
+//  directory. "./" prefixes in the relative files will be automatically
+//  removed, but the rest of a relative path must be a suffix of a path in
+//  the compile command line database.
+//
+//  For example, to use clang-check on all files in a subtree of the source
+//  tree, use:
+//
+//    /path/in/subtree $ find . -name '*.cpp'| xargs clang-check /path/to/source
+//
