   6 # This script executes the command given as the first argument, strips
   7 # cxx_destruct from stdout, and redirects the remaining stdout to the file given
   8 # as the second argument.
   9 #
  10 # Example: Write the text 'foo' to a file called out.txt:
  11 #   RedirectStdout.sh "echo foo" out.txt
  12 #
  13 # This script is invoked from iossim.gyp in order to redirect the output of
  14 # class-dump to a file (because gyp actions don't support redirecting output).
  15 # This script also removes all lines with cxx_destruct. Perhaps newer versions
  16 # of class-dump will fix this issue.  As of 3.5, 'cxx_destruct' still exists.
