   4 # - format source tree according to OpenSSL coding style using indent
   5 #
   6 # usage:
   7 #   openssl-format-source [-v] [-n] [file|directory] ...
   8 #
   9 # note: the indent options assume GNU indent v2.2.10 which was released
  10 #       Feb-2009 so if you have an older indent the options may not
  11 #       match what is expected
  12 #
  13 # any marked block comment blocks have to be moved to align manually after
  14 # the reformatting has been completed as marking a block causes indent to
  15 # not move it at all ...
