 /// \file
 /// \brief Defines a driver for translating PNaCl bitcode into native code.
 ///
 /// The driver can either directly parse the binary bitcode file, or use LLVM
 /// routines to parse a textual bitcode file into LLVM IR and then convert LLVM
 /// IR into ICE. In either case, the high-level ICE is then compiled down to
 /// native code, as either an ELF object file or a textual asm file.
