die <<EEE unless @ARGV;
Usage: $0 func1 [func2 [ ...] ]
This filter (stdin->stdout) removes lines from dbug trace that were generated
by specified functions and all functions down the call stack. Produces the
same effect as if the original source had DBUG_PUSH(""); right after
DBUG_ENTER() and DBUG_POP(); right before DBUG_RETURN in every such a function.
