-Welcome to the repository of extra Clang Tools.  This repository holds tools
-that are developed as part of the LLVM compiler infrastructure project and the
-Clang frontend.  These tools are kept in a separate "extra" repository to
-allow lighter weight checkouts of the core Clang codebase.
-
-This repository is only intended to be checked out inside of a full LLVM+Clang
-tree, and in the 'tools/extra' subdirectory of the Clang checkout.
-
-All discussion regarding Clang, Clang-based tools, and code in this repository
-should be held using the standard Clang mailing lists:
-  http://lists.cs.uiuc.edu/mailman/listinfo/cfe-dev
-
-Code review for this tree should take place on the standard Clang patch and
-commit lists:
-  http://lists.cs.uiuc.edu/mailman/listinfo/cfe-commits
-
-If you find a bug in these tools, please file it in the LLVM bug tracker:
-  http://llvm.org/bugs/

-/// \brief The matcher used for array-like containers (pseudoarrays).
-///
-/// This matcher is more flexible than array-based loops. It will match
-/// loops of the following textual forms (regardless of whether the
-/// iterator type is actually a pointer type or a class type):
-///
-/// Assuming f, g, and h are of type containerType::iterator,
-///   for (int i = 0, j = container.size(); f < g; ++h) { ... }
-///   for (int i = 0; f < container.size(); ++h) { ... }
-/// The following string identifiers are bound to the parts of the AST:
-///   InitVarName: 'i' (as a VarDecl)
-///   ConditionVarName: 'f' (as a VarDecl)
-///   LoopName: The entire for loop (as a ForStmt)
-///   In the first example only:
-///     EndVarName: 'j' (as a VarDecl)
-///     ConditionEndVarName: 'g' (as a VarDecl)
-///   In the second example only:
-///     EndCallName: 'container.size()' (as a CXXMemberCallExpr)
-///
-/// Client code will need to make sure that:
-///   - The index variables 'i', 'f', and 'h' are the same
-///   - The containers on which 'size()' is called is the container indexed
-///   - The index variable is only used in overloaded operator[] or
-///     container.at()
-///   - If the end iterator variable 'g' is defined, it is the same as 'j'
-///   - The container's iterators would not be invalidated during the loop

-//===---- tools/extra/ToolTemplate.cpp - Template for refactoring 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 an empty refactoring tool using the clang tooling.
-//  The goal is to lower the "barrier to entry" for writing refactoring tools.
-//
-//  Usage:
-//  tool-template <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 tool-template on all files in a subtree of the
-//  source tree, use:
-//
-//    /path/in/subtree $ find . -name '*.cpp'|
-//        xargs tool-template /path/to/build
-//
