=item skiptest

A boolean indicating whether or not to skip tests when installing modules.
Defaults to 'false'.

=cut

        $Conf->{'conf'}->{'skiptest'} = 0;

=item storable

A boolean indicating whether or not to use C<Storable> to write compiled
source file information to disk. This makes for faster startup and look
up times, but takes extra diskspace. Defaults to 'true' if you have 
C<Storable> installed and 'false' if you don't.

=cut

       $Conf->{'conf'}->{'storable'} = 
                        ( check_install( module => 'Storable' ) ? 1 : 0 );

=item timeout

Digit indicating the time before a fetch request times out (in seconds).
Defaults to 300.

=cut

        $Conf->{'conf'}->{'timeout'} = 300;

=item verbose

A boolean indicating whether or not C<CPANPLUS> runs in verbose mode.
Defaults to 'true' if you have the environment variable 
C<PERL5_CPANPLUS_VERBOSE> set to true, 'false' otherwise.

It is recommended you run with verbose enabled, but it is disabled
for historical reasons.

=cut

        $Conf->{'conf'}->{'verbose'} = $ENV{PERL5_CPANPLUS_VERBOSE} || 0;

=item write_install_log

A boolean indicating whether or not to write install logs after installing
a module using the interactive shell. Defaults to 'true'.

A string holding the path to your C<make> binary. Looks for the C<make>
program used to build perl or failing that, a C<make> in your path.

A string holding the path to your C<sudo> binary if your install path
requires super user permissions. Looks for C<sudo> in your path, or
