-//===- examples/Tooling/ClangCheck.cpp - Clang check tool -----------------===//
-//
-// The LLVM Compiler Infrastructure
-//
-// This file is distributed under the University of Illinois Open Source
-// License. See LICENSE.TXT for details.
-//
-//===----------------------------------------------------------------------===//
-//
-// 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
-//
