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