961 CPAN is the world-wide archive of perl resources. It consists of about
962 300 sites that all replicate the same contents around the globe. Many
963 countries have at least one CPAN site already. The resources found on
964 CPAN are easily accessible with the CPAN.pm module. If you want to use
965 CPAN.pm, lots of things have to be configured. Fortunately, most of
966 them can be determined automatically. If you prefer the automatic
967 configuration, answer 'yes' below.
969 If you prefer to enter a dialog instead, you can answer 'no' to this
970 question and I'll let you configure in small steps one thing after the
971 other. (Note: you can revisit this dialog anytime later by typing 'o
972 conf init' at the cpan prompt.)
978 The following questions are intended to help you with the
979 configuration. The CPAN module needs a directory of its own to cache
980 important index files and maybe keep a temporary mirror of CPAN files.
981 This may be a site-wide or a personal directory.

1015 qq{Until version 1.88 CPAN.pm never trusted the contents of the
1016 build_dir directory between sessions. Since 1.88_58 CPAN.pm has a
1017 YAML-based mechanism that makes it possible to share the contents of
1018 the build_dir/ directory between different sessions with the same
1019 version of perl. People who prefer to test things several days before
1020 installing will like this feature because it safes a lot of time.

1038 default options for CPAN.pm and the environment can be overridden and
1039 dialog sequences can be stored that can later be executed by an
1040 Expect.pm object. The CPAN.pm distribution comes with some prefab YAML

1090 upload their software to CPAN bear names that are outside the ASCII
1091 range. If your terminal supports UTF-8, you should say no to the next
1092 question. If it supports ISO-8859-1 (also known as LATIN1) then you
1093 should say yes. If it supports neither, your answer does not matter

1129 The CPAN module can detect when a module which you are trying to build
1130 depends on prerequisites. If this happens, it can build the

1132 confirmation ('ask'), or just ignore them ('ignore'). Please set your
1133 policy to one of the three values.

1140 check_sigs_intro => qq{
1142 CPAN packages can be digitally signed by authors and thus verified
1143 with the security provided by strong cryptography. The exact mechanism
1144 is defined in the Module::Signature module. While this is generally
1145 considered a good thing, it is not always convenient to the end user
1146 to install modules that are signed incorrectly or where the key of the
1147 author is not available or where some prerequisite for
1148 Module::Signature has a bug and so on.
1150 With the check_sigs parameter you can turn signature checking on and
1151 off. The default is off for now because the whole tool chain for the
1152 functionality is not yet considered mature by some. The author of
1153 CPAN.pm would recommend setting it to true most of the time and
1154 turning it off only if it turns out to be annoying.
1156 Note that if you do not have Module::Signature installed, no signature
1157 checks will be performed at all.

1168 The goal of the CPAN Testers project (http://testers.cpan.org/) is to
1169 test as many CPAN packages as possible on as many platforms as
1170 possible. This provides valuable feedback to module authors and
1171 potential users to identify bugs or platform compatibility issues and
1172 improves the overall quality and value of CPAN.
1174 One way you can contribute is to send test results for each module
1175 that you install. If you install the CPAN::Reporter module, you have
1176 the option to automatically generate and email test reports to CPAN
1177 Testers whenever you run tests on a CPAN package.
1179 See the CPAN::Reporter documentation for additional details and
1180 configuration settings. If your firewall blocks outgoing email,
1181 you will need to configure CPAN::Reporter before sending reports.
