.Sp
If you set this value to 0, these processes will wait forever. This is
the default and recommended setting.
.Sp
Timeout for inactivity during {Makefile,Build}.PL?
.IP "index_expire" 2
.IX Item "index_expire"
The \s-1CPAN\s0 indexes are usually rebuilt once or twice per hour, but the
typical \s-1CPAN\s0 mirror mirrors only once or twice per day. Depending on
the quality of your mirror and your desire to be on the bleeding edge,
you may want to set the following value to more or less than one day
(which is the default). It determines after how many days \s-1CPAN\s0.pm
downloads new indexes.
.Sp
Let the index expire after how many days?
.IP "inhibit_startup_message" 2
.IX Item "inhibit_startup_message"
When the \s-1CPAN\s0 shell is started it normally displays a greeting message
that contains the running version and the status of readline support.
.Sp
Do you want to turn this message off?
.IP "keep_source_where" 2
.IX Item "keep_source_where"
Unless you are accessing the \s-1CPAN\s0 on your filesystem via a file: \s-1URL\s0,
\&\s-1CPAN\s0.pm needs to keep the source files it downloads somewhere. Please
supply a directory where the downloaded files are to be kept.
.Sp
Download target directory?
.IP "load_module_verbosity" 2
.IX Item "load_module_verbosity"
When \s-1CPAN\s0.pm loads a module it needs for some optional feature, it
usually reports about module name and version. Choose 'v' to get this
message, 'none' to suppress it.
.Sp
Verbosity level for loading modules (none or v)?
.IP "makepl_arg" 2
.IX Item "makepl_arg"
Every Makefile.PL is run by perl in a separate process. Likewise we
run 'make' and 'make install' in separate processes. If you have
any parameters (e.g. \s-1PREFIX\s0, \s-1LIB\s0, \s-1UNINST\s0 or the like) you want to
pass to the calls, please specify them here.
.Sp
If you don't understand this question, just press \s-1ENTER\s0.

Your choice:
.IP "make_install_make_command" 2
.IX Item "make_install_make_command"
Do you want to use a different make command for 'make install'?
Cautious people will probably prefer:

\&    su root \-c make
\& or
\&    sudo make
\& or
\&    /path1/to/sudo \-u admin_account /path2/to/make
.Ve
.Sp
or some such. Your choice:
.IP "mbuildpl_arg" 2
.IX Item "mbuildpl_arg"
A Build.PL is run by perl in a separate process. Likewise we run
\&'./Build' and './Build install' in separate processes. If you have any
parameters you want to pass to the calls, please specify them here.
.Sp
Typical frequently used settings:
.Sp
.Vb 1
\&    \-\-install_base /home/xxx             # different installation directory

.IP "pager" 2
.IX Item "pager"
What is your favorite pager program?
.IP "prefer_installer" 2
.IX Item "prefer_installer"
When you have Module::Build installed and a module comes with both a
Makefile.PL and a Build.PL, which shall have precedence?
.Sp
The main two standard installer modules are the old and well
established ExtUtils::MakeMaker (for short: \s-1EUMM\s0) which uses the
Makefile.PL. And the next generation installer Module::Build (\s-1MB\s0)
which works with the Build.PL (and often comes with a Makefile.PL
too). If a module comes only with one of the two we will use that one
but if both are supplied then a decision must be made between \s-1EUMM\s0 and
\&\s-1MB\s0. See also http://rt.cpan.org/Ticket/Display.html?id=29235 for a
discussion about the right default.
.Sp
Or, as a third option you can choose \s-1RAND\s0 which will make a random
decision (something regular \s-1CPAN\s0 testers will enjoy).
.Sp
In case you can choose between running a Makefile.PL or a Build.PL,
which installer would you prefer (\s-1EUMM\s0 or \s-1MB\s0 or \s-1RAND\s0)?
.IP "prefs_dir" 2
.IX Item "prefs_dir"
\&\s-1CPAN\s0.pm can store customized build environments based on regular
expressions for distribution names. These are \s-1YAML\s0 files where the
default options for \s-1CPAN\s0.pm and the environment can be overridden and
dialog sequences can be stored that can later be executed by an
Expect.pm object. The \s-1CPAN\s0.pm distribution comes with some prefab \s-1YAML\s0
files that cover sample distributions that can be used as blueprints
to store one own prefs. Please check out the distroprefs/ directory of
the \s-1CPAN\s0.pm distribution to get a quick start into the prefs system.
.Sp
Directory where to store default options/environment/dialogs for
building modules that need some customization?
.IP "prerequisites_policy" 2
.IX Item "prerequisites_policy"
The \s-1CPAN\s0 module can detect when a module which you are trying to build
depends on prerequisites. If this happens, it can build the
prerequisites for you automatically ('follow'), ask you for
confirmation ('ask'), or just ignore them ('ignore'). Please set your
policy to one of the three values.
.Sp
Policy on building prerequisites (follow, ask or ignore)?
.IP "randomize_urllist" 2
.IX Item "randomize_urllist"
\&\s-1CPAN\s0.pm can introduce some randomness when using hosts for download
that are configured in the urllist parameter. Enter a numeric value
between 0 and 1 to indicate how often you want to let \s-1CPAN\s0.pm try a
random host from the urllist. A value of one specifies to always use a
random host as the first try. A value of zero means no randomness at
all. Anything in between specifies how often, on average, a random
host should be tried first.
.Sp
Randomize parameter
.IP "scan_cache" 2
.IX Item "scan_cache"
By default, each time the \s-1CPAN\s0 module is started, cache scanning is
performed to keep the cache size in sync. To prevent this, answer
\&'never'.
.Sp
Perform cache scanning (atstart or never)?
.IP "shell" 2
.IX Item "shell"
What is your favorite shell?
.IP "show_unparsable_versions" 2
.IX Item "show_unparsable_versions"
During the 'r' command \s-1CPAN\s0.pm finds modules without version number.
When the command finishes, it prints a report about this. If you
want this report to be very verbose, say yes to the following
variable.
.Sp
Show all individual modules that have no \f(CW$VERSION\fR?
.IP "show_upload_date" 2
.IX Item "show_upload_date"
The 'd' and the 'm' command normally only show you information they
have in their in-memory database and thus will never connect to the
internet. If you set the 'show_upload_date' variable to true, 'm' and
\&'d' will additionally show you the upload date of the module or
distribution. Per default this feature is off because it may require a
net connection to get at the upload date.
.Sp
Always try to show upload date with 'd' and 'm' command (yes/no)?
.IP "show_zero_versions" 2
.IX Item "show_zero_versions"
During the 'r' command \s-1CPAN\s0.pm finds modules with a version number of
zero. When the command finishes, it prints a report about this. If you
want this report to be very verbose, say yes to the following
variable.
.Sp
Show all individual modules that have a \f(CW$VERSION\fR of zero?
.IP "tar_verbosity" 2
.IX Item "tar_verbosity"
When \s-1CPAN\s0.pm uses the tar command, which switch for the verbosity
shall be used? Choose 'none' for quiet operation, 'v' for file
name listing, 'vv' for full listing.
.Sp
Tar command verbosity level (none or v or vv)?
.IP "term_is_latin" 2
.IX Item "term_is_latin"
The next option deals with the charset (aka character set) your
terminal supports. In general, \s-1CPAN\s0 is English speaking territory, so
the charset does not matter much but some \s-1CPAN\s0 have names that are
outside the \s-1ASCII\s0 range. If your terminal supports \s-1UTF\-8\s0, you should
say no to the next question. If it expects \s-1ISO\-8859\-1\s0 (also known as
\&\s-1LATIN1\s0) then you should say yes. If it supports neither, your answer
does not matter because you will not be able to read the names of some
authors anyway. If you answer no, names will be output in \s-1UTF\-8\s0.
.Sp
Your terminal expects \s-1ISO\-8859\-1\s0 (yes/no)?
.IP "term_ornaments" 2
.IX Item "term_ornaments"
When using Term::ReadLine, you can turn ornaments on so that your
input stands out against the output from \s-1CPAN\s0.pm.
.Sp
Do you want to turn ornaments on?
.IP "test_report" 2
.IX Item "test_report"
The goal of the \s-1CPAN\s0 Testers project (http://testers.cpan.org/) is to
test as many \s-1CPAN\s0 packages as possible on as many platforms as
possible.  This provides valuable feedback to module authors and
potential users to identify bugs or platform compatibility issues and
improves the overall quality and value of \s-1CPAN\s0.
.Sp
One way you can contribute is to send test results for each module
that you install.  If you install the CPAN::Reporter module, you have
the option to automatically generate and email test reports to \s-1CPAN\s0
Testers whenever you run tests on a \s-1CPAN\s0 package.
.Sp
See the CPAN::Reporter documentation for additional details and
configuration settings.  If your firewall blocks outgoing email,
you will need to configure CPAN::Reporter before sending reports.
.Sp
Email test reports if CPAN::Reporter is installed (yes/no)?
.IP "use_sqlite" 2
.IX Item "use_sqlite"
CPAN::SQLite is a layer between the index files that are downloaded
from the \s-1CPAN\s0 and \s-1CPAN\s0.pm that speeds up metadata queries and reduces
memory consumption of \s-1CPAN\s0.pm considerably.
.Sp
Use CPAN::SQLite if available? (yes/no)?
.IP "yaml_load_code" 2
.IX Item "yaml_load_code"
Both \s-1YAML\s0.pm and YAML::Syck are capable of deserialising code. As this requires
a string eval, which might be a security risk, you can use this option to
enable or disable the deserialisation of code.
.Sp
Do you want to enable code deserialisation (yes/no)?
.IP "yaml_module" 2
.IX Item "yaml_module"
At the time of this writing there are two competing \s-1YAML\s0 modules,
\&\s-1YAML\s0.pm and YAML::Syck. The latter is faster but needs a C compiler
installed on your system. There may be more alternative \s-1YAML\s0
conforming modules but at the time of writing a potential third
player, YAML::Tiny, seemed not powerful enough to work with \s-1CPAN\s0.pm.
.Sp
Which \s-1YAML\s0 implementation would you prefer?
