  14. # openssl-format-source [-v] [-n] [file|directory] ...
  15. #
  16. # note: the indent options assume GNU indent v2.2.10 which was released
  17. # Feb-2009 so if you have an older indent the options may not
  18. # match what is expected
  19. #
  20. # any marked block comment blocks have to be moved to align manually after
  21. # the reformatting has been completed as marking a block causes indent to
  22. # not move it at all ...
