53 | ||
54 | XXX Remove this section if not applicable. | |
55 | ||
56 | The following modules will be removed from the core distribution in a | |
57 | future release, and will at that time need to be installed from CPAN. | |
58 | Distributions on CPAN which require these modules will need to list them as | |
59 | prerequisites. | |
60 | ||
61 | The core versions of these modules will now issue C<"deprecated">-category | |
62 | warnings to alert you to this fact. To silence these deprecation warnings, | |
63 | install the modules in question from CPAN. | |
64 | ||
65 | Note that these are (with rare exceptions) fine modules that you are encouraged | |
66 | to continue to use. Their disinclusion from core primarily hinges on their | |
67 | necessity to bootstrapping a fully functional, CPAN-capable Perl installation, | |
68 | not usually on concerns over their design. | |

107 | manually-added details don't match the automatically-generated ones, the | |
