-"""This takes three command-line arguments:
-      MUNGE-PHDR-PROGRAM      file name of program built from
-                              nacl_helper_bootstrap_munge_phdr.c
-      INFILE                  raw linked ELF file name
-      OUTFILE                 output file name
-
-We just run the MUNGE-PHDR-PROGRAM on a copy of INFILE.
-That modifies the file in place.  Then we move it to OUTFILE.
-
-We only have this wrapper script because nacl_helper_bootstrap_munge_phdr.c
-wants to modify a file in place (and it would be a much longer and more
-fragile program if it created a fresh ELF output file instead).
