perl-Devel-Trace

If you run your program with 'perl -d:Trace program', this module will
print a message to standard error just before each line is executed. For
example, if your program looks like this:
    print "Statement 1 at line 4\n";
    print "Statement 2 at line 5\n";
    print "Call to sub x returns ", &x(), " at line 6.\n";

    exit 0;


    sub x {
      print "In sub x at line 12.\n";
      return 13;
    }


Then the 'Trace' output will look like this:
    >> ./test:4: print "Statement 1 at line 4\n";
    >> ./test:5: print "Statement 2 at line 5\n";
    >> ./test:6: print "Call to sub x returns ", &x(), " at line 6.\n";
    >> ./test:12:   print "In sub x at line 12.\n";
    >> ./test:13:   return 13;
    >> ./test:8: exit 0;


This is something like the shell's '-x' option.
