3 | # This library is no longer being maintained, and is included for backward | |
4 | # compatibility with Perl 4 programs which may require it. | |
5 | # | |
6 | # In particular, this should not be used as an example of modern Perl | |
7 | # programming techniques. | |
8 | # | |
9 | # Suggested alternatives: Getopt::Long or Getopt::Std | |
