=item term_ornaments

When using Term::ReadLine, you can turn ornaments on so that your
input stands out against the output from CPAN.pm.

Do you want to turn ornaments on?

=item test_report

The goal of the CPAN Testers project (http://testers.cpan.org/) is to
test as many CPAN 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 CPAN.

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 deliver test reports to CPAN
Testers whenever you run tests on a CPAN package.

See the CPAN::Reporter documentation for additional details and
configuration settings.  If your firewall blocks outgoing traffic,
you may need to configure CPAN::Reporter before sending reports.

Generate test reports if CPAN::Reporter is installed (yes/no)?

=item perl5lib_verbosity

When CPAN.pm extends @INC via PERL5LIB, it prints a list of
directories added (or a summary of how many directories are
added).  Choose 'v' to get this message, 'none' to suppress it.

Verbosity level for PERL5LIB changes (none or v)?

=item prefer_external_tar

Per default all untar operations are done with the perl module
Archive::Tar; by setting this variable to true the external tar
command is used if available; on Unix this is usually preferred
because they have a reliable and fast gnutar implementation.

Use the external tar program instead of Archive::Tar?

=item trust_test_report_history

When a distribution has already been tested by CPAN::Reporter on
this machine, CPAN can skip the test phase and just rely on the
test report history instead.

Note that this will not apply to distributions that failed tests
because of missing dependencies.  Also, tests can be run
regardless of the history using "force".

Do you want to rely on the test report history (yes/no)?

=item urllist_ping_external

When automatic selection of the nearest cpan mirrors is performed,
turn on the use of the external ping via Net::Ping::External. This is
recommended in the case the local network has a transparent proxy.

Do you want to use the external ping command when autoselecting
mirrors?

=item urllist_ping_verbose

When automatic selection of the nearest cpan mirrors is performed,
this option can be used to turn on verbosity during the selection
process.

Do you want to see verbosity turned on when autoselecting mirrors?

=item use_prompt_default

When this is true, CPAN will set PERL_MM_USE_DEFAULT to a true
value.  This causes ExtUtils::MakeMaker (and compatible) prompts
to use default values instead of stopping to prompt you to answer
questions. It also sets NONINTERACTIVE_TESTING to a true value to
signal more generally that distributions should not try to
interact with you.

Do you want to use prompt defaults (yes/no)?

=item use_sqlite

CPAN::SQLite is a layer between the index files that are downloaded
from the CPAN and CPAN.pm that speeds up metadata queries and reduces
memory consumption of CPAN.pm considerably.

Use CPAN::SQLite if available? (yes/no)?

=item version_timeout

This timeout prevents CPAN from hanging when trying to parse a
pathologically coded $VERSION from a module.

The default is 15 seconds.  If you set this value to 0, no timeout
will occur, but this is not recommended.

Timeout for parsing module versions?

=item yaml_load_code

Both YAML.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 via
CPAN::DeferredCode. (Note: This does not work under perl 5.6)

Do you want to enable code deserialisation (yes/no)?

=item yaml_module

At the time of this writing (2009-03) there are three YAML
implementations working: YAML, YAML::Syck, and YAML::XS. The latter
two are faster but need a C compiler installed on your system. There
may be more alternative YAML conforming modules. When I tried two
other players, YAML::Tiny and YAML::Perl, they seemed not powerful
enough to work with CPAN.pm. This may have changed in the meantime.

Which YAML implementation would you prefer?
