 // This tool may be invoked in the following manner:
-//  llvm-bcanalyzer [options]      - Read LLVM bitcode from stdin
-//  llvm-bcanalyzer [options] x.bc - Read LLVM bitcode from the x.bc file
+//  pnacl-bcanalyzer [options]      - Read frozen PNaCl bitcode from stdin
+//  pnacl-bcanalyzer [options] x.bc - Read frozen PNaCl bitcode from the x.bc
+//                                   file
 //
 //  Options:
 //      --help      - Output information about command line switches
 //      --dump      - Dump low-level bitcode structure in readable format
 //
 // This tool provides analytical information about a bitcode file. It is
 // intended as an aid to developers of bitcode reading and writing software. It
 // produces on std::out a summary of the bitcode file that shows various
 // statistics about the contents of the file. By default this information is
 // detailed and contains information about individual bitcode blocks and the
 // functions in the module.
 // The tool is also able to print a bitcode file in a straight forward text
 // format that shows the containment and relationships of the information in
 // the bitcode file (-dump option).
