# Please set INPLACE_SUFFIX to make a backup copy. For example, you may
# want to set INPLACE_SUFFIX to .bak on the command line or in a BEGIN rule.
# By default, each filename on the command line will be edited inplace.
# But you can selectively disable this by adding an inplace=0 argument
# prior to files that you do not want to process this way. You can then
# reenable it later on the commandline by putting inplace=1 before files
# that you wish to be subject to inplace editing.
# N.B. We call inplace_end() in the BEGINFILE and END rules so that any
# actions in an ENDFILE rule will be redirected as expected.
