The filename `C<->' may be used to read standard input. The edit script is composed from arguments of B<-e> options and script-files, in the given order. A single script argument may be specified as the first parameter. If this program is invoked with the name F, it will act as a sed-to-Perl translator. See L<"sed Script Translation">. B returns an exit code of 0 on success or >0 if an error occurred. =head1 OPTIONS =over 4 =item B<-a> A file specified as argument to the B edit command is by default opened before input processing starts. Using B<-a>, opening of such files is delayed until the first line is actually written to the file. =item B<-e> I
