cwd         Cwd::cwd

Preferred method for determining the current working directory?

=item halt_on_failure

Normaly, CPAN.pm continues processing the full list of targets and
dependencies, even if one of them fails.  However, you can specify 
that CPAN should halt after the first failure. 

Do you want to halt on failure (yes/no)?

=item histfile

If you have one of the readline packages (Term::ReadLine::Perl,
Term::ReadLine::Gnu, possibly others) installed, the interactive CPAN
shell will have history support. The next two questions deal with the
filename of the history file and with its size. If you do not want to
set this variable, please hit SPACE RETURN to the following question.

File to save your history?

=item histsize

Number of lines to save?

=item inactivity_timeout

Sometimes you may wish to leave the processes run by CPAN alone
without caring about them. Because the Makefile.PL or the Build.PL
sometimes contains question you're expected to answer, you can set a
timer that will kill a 'perl Makefile.PL' process after the specified
time in seconds.

If you set this value to 0, these processes will wait forever. This is
the default and recommended setting.

Timeout for inactivity during {Makefile,Build}.PL?

=item index_expire

The CPAN indexes are usually rebuilt once or twice per hour, but the
typical CPAN 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 CPAN.pm
downloads new indexes.

Let the index expire after how many days?

=item inhibit_startup_message

When the CPAN shell is started it normally displays a greeting message
that contains the running version and the status of readline support.

Do you want to turn this message off?

=item keep_source_where

Unless you are accessing the CPAN on your filesystem via a file: URL,
CPAN.pm needs to keep the source files it downloads somewhere. Please
supply a directory where the downloaded files are to be kept.

Download target directory?

=item load_module_verbosity

When CPAN.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.

Verbosity level for loading modules (none or v)?

=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. PREFIX, UNINST or the like) you want to
pass to the calls, please specify them here.

If you don't understand this question, just press ENTER.

Typical frequently used settings:

    PREFIX=~/perl    # non-root users (please see manual for more hints)

Parameters for the 'perl Makefile.PL' command?

=item make_arg

Parameters for the 'make' command? Typical frequently used setting:

    -j3              # dual processor system (on GNU make)
