+// This file defines a driver for translating PNaCl bitcode into native code.
+// It 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.
