5 | # This file is automatically included if you do perl -d. |
6 | # It's probably not useful to include this yourself. |
7 | # |
8 | # Perl supplies the values for @line and %sub. It effectively inserts |
9 | # a do DB'DB(<linenum>); in front of every place that can |
10 | # have a breakpoint. It also inserts a do 'perldb.pl' before the first line. |
