-# 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).
