931 CPAN is the world-wide archive of perl resources. It consists of about
932 300 sites that all replicate the same contents around the globe. Many
933 countries have at least one CPAN site already. The resources found on
934 CPAN are easily accessible with the CPAN.pm module. If you want to use
935 CPAN.pm, lots of things have to be configured. Fortunately, most of
936 them can be determined automatically. If you prefer the automatic
937 configuration, answer 'yes' below.
939 If you prefer to enter a dialog instead, you can answer 'no' to this
940 question and I'll let you configure in small steps one thing after the
941 other. (Note: you can revisit this dialog anytime later by typing 'o
942 conf init' at the cpan prompt.)
948 The following questions are intended to help you with the
949 configuration. The CPAN module needs a directory of its own to cache
950 important index files and maybe keep a temporary mirror of CPAN files.
951 This may be a site-wide or a personal directory.
955 # cpan_home => qq{ },
957 cpan_home_where => qq{
959 First of all, I\'d like to create this directory. Where?
963 keep_source_where => qq{
965 Unless you are accessing the CPAN via the filesystem directly CPAN.pm
966 needs to keep the source files it downloads somewhere. Please supply a
967 directory where the downloaded files are to be kept.},
969 build_cache_intro => qq{
971 How big should the disk cache be for keeping the build directories
972 with all the intermediate files\?
977 "Cache size for build directory (in MB)?",
981 "Directory where the build process takes place?",
983 prefs_dir_intro => qq{
985 CPAN.pm can store customized build environments based on regular
986 expressions for distribution names. These are YAML files where the
987 default options for CPAN.pm and the environment can be overridden and
988 dialog sequences can be stored that can later be executed by an
989 Expect.pm object. The CPAN.pm distribution comes with some prefab YAML
990 files that cover sample distributions that can be used as blueprints
991 to store one own prefs. Please check out the distroprefs/ directory of
992 the CPAN.pm distribution to get a quick start into the prefs system.
998 "Directory where to store default options/environment/dialogs for
999 building modules that need some customization?",
1001 scan_cache_intro => qq{
1003 By default, each time the CPAN module is started, cache scanning is
1004 performed to keep the cache size in sync. To prevent this, answer
1009 scan_cache => "Perform cache scanning (atstart or never)?",
1011 cache_metadata_intro => qq{
1013 To considerably speed up the initial CPAN shell startup, it is
1014 possible to use Storable to create a cache of metadata. If Storable
1015 is not available, the normal index mechanism will be used.
1019 cache_metadata => qq{Cache metadata (yes/no)?},
1021 term_is_latin_intro => qq{
1023 The next option deals with the charset (aka character set) your
1024 terminal supports. In general, CPAN is English speaking territory, so
1025 the charset does not matter much, but some of the aliens out there who
1026 upload their software to CPAN bear names that are outside the ASCII
1027 range. If your terminal supports UTF-8, you should say no to the next
1028 question. If it supports ISO-8859-1 (also known as LATIN1) then you
1029 should say yes. If it supports neither, your answer does not matter
1030 because you will not be able to read the names of some authors
1031 anyway. If you answer no, names will be output in UTF-8.
1035 term_is_latin => qq{Your terminal expects ISO-8859-1 (yes/no)?},
1037 histfile_intro => qq{
1039 If you have one of the readline packages (Term::ReadLine::Perl,
1040 Term::ReadLine::Gnu, possibly others) installed, the interactive CPAN
1041 shell will have history support. The next two questions deal with the
1042 filename of the history file and with its size. If you do not want to
1043 set this variable, please hit SPACE RETURN to the following question.
1047 histfile => qq{File to save your history?},
1049 show_upload_date_intro => qq{
1051 The 'd' and the 'm' command normally only show you information they
1052 have in their in-memory database and thus will never connect to the
1053 internet. If you set the 'show_upload_date' variable to true, 'm' and
1054 'd' will additionally show you the upload date of the module or
1055 distribution. Per default this feature is off because it may require a
1056 net connection to get at the upload date.
1061 "Always try to show upload date with 'd' and 'm' command (yes/no)?",
1063 prerequisites_policy_intro => qq{
1065 The CPAN module can detect when a module which you are trying to build
1066 depends on prerequisites. If this happens, it can build the
1067 prerequisites for you automatically ('follow'), ask you for
1068 confirmation ('ask'), or just ignore them ('ignore'). Please set your
1069 policy to one of the three values.
1073 prerequisites_policy =>
1074 "Policy on building prerequisites (follow, ask or ignore)?",
1076 check_sigs_intro => qq{
1078 CPAN packages can be digitally signed by authors and thus verified
1079 with the security provided by strong cryptography. The exact mechanism
1080 is defined in the Module::Signature module. While this is generally
1081 considered a good thing, it is not always convenient to the end user
1082 to install modules that are signed incorrectly or where the key of the
1083 author is not available or where some prerequisite for
1084 Module::Signature has a bug and so on.
1086 With the check_sigs parameter you can turn signature checking on and
1087 off. The default is off for now because the whole tool chain for the
1088 functionality is not yet considered mature by some. The author of
1089 CPAN.pm would recommend setting it to true most of the time and
1090 turning it off only if it turns out to be annoying.
1092 Note that if you do not have Module::Signature installed, no signature
1093 checks will be performed at all.
1098 qq{Always try to check and verify signatures if a SIGNATURE file is in the package
1099 and Module::Signature is installed (yes/no)?},
1101 test_report_intro =>
1104 The goal of the CPAN Testers project (http://testers.cpan.org/) is to
1105 test as many CPAN packages as possible on as many platforms as
1106 possible. This provides valuable feedback to module authors and
1107 potential users to identify bugs or platform compatibility issues and
1108 improves the overall quality and value of CPAN.
1110 One way you can contribute is to send test results for each module
1111 that you install. If you install the CPAN::Reporter module, you have
1112 the option to automatically generate and email test reports to CPAN
1113 Testers whenever you run tests on a CPAN package.
1115 See the CPAN::Reporter documentation for additional details and
1116 configuration settings. If your firewall blocks outgoing email,
1117 you will need to configure CPAN::Reporter before sending reports.
1122 qq{Email test reports if CPAN::Reporter is installed (yes/no)?},
1124 external_progs => qq{
1126 The CPAN module will need a few external programs to work properly.
1127 Please correct me, if I guess the wrong path for a program. Don\'t
1128 panic if you do not have some of them, just press ENTER for those. To
1129 disable the use of a program, you can type a space followed by ENTER.
1133 prefer_installer_intro => qq{
1135 When you have Module::Build installed and a module comes with both a
1136 Makefile.PL and a Build.PL, which shall have precedence? The two
1137 installer modules we have are the old and well established

1231 Typical frequently used setting:

1239 inactivity_timeout_intro => qq{
1241 Sometimes you may wish to leave the processes run by CPAN alone
1242 without caring about them. Because the Makefile.PL or the Build.PL
1243 sometimes contains question you\'re expected to answer, you can set a
1244 timer that will kill a 'perl Makefile.PL' process after the specified

1258 If you\'re accessing the net via proxies, you can specify them in the
1259 CPAN configuration or via environment variables. The variable in
1260 the \$CPAN::Config takes precedence.
1266 If your proxy is an authenticating proxy, you can store your username
1267 permanently. If you do not want that, just press RETURN. You will then
1268 be asked for your username in every future session.

1291 URLs of CPAN mirrors in the countries you selected, along with
1292 previously selected URLs. Select some of those URLs, or just keep the

1319 CPAN.pm changes the current working directory often and needs to
1320 determine its own current working directory. Per default it uses

1333 index_expire_intro => qq{
1335 The CPAN indexes are usually rebuilt once or twice per hour, but the
1336 typical CPAN mirror mirrors only once or twice per day. Depending on
1337 the quality of your mirror and your desire to be on the bleeding edge,
1338 you may want to set the following value to more or less than one day
