  // CK-HELP: {{.*}}OVERVIEW: A tool to bundle several input files of the specified type <type>
  // CK-HELP: {{.*}}referring to the same source file but different targets into a single
  // CK-HELP: {{.*}}one. The resulting file can also be unbundled into different files by
  // CK-HELP: {{.*}}this tool if -unbundle is provided.
  // CK-HELP: {{.*}}USAGE: clang-offload-bundler [options]
  // CK-HELP: {{.*}}-inputs=<string>  - [<input file>,...]
  // CK-HELP: {{.*}}-outputs=<string> - [<output file>,...]
  // CK-HELP: {{.*}}-targets=<string> - [<offload kind>-<target triple>,...]
  // CK-HELP: {{.*}}-type=<string>    - Type of the files to be bundled/unbundled.
  // CK-HELP: {{.*}}Current supported types are:
  // CK-HELP: {{.*}}i {{.*}}- cpp-output
  // CK-HELP: {{.*}}ii {{.*}}- c++-cpp-output
  // CK-HELP: {{.*}}ll {{.*}}- llvm
  // CK-HELP: {{.*}}bc {{.*}}- llvm-bc
  // CK-HELP: {{.*}}s {{.*}}- assembler
  // CK-HELP: {{.*}}o {{.*}}- object
  // CK-HELP: {{.*}}gch {{.*}}- precompiled-header
  // CK-HELP: {{.*}}ast {{.*}}- clang AST file
  // CK-HELP: {{.*}}-unbundle {{.*}}- Unbundle bundled file into several output files.
