FCM::System::Make::Build::Task::Archive
=head1 SYNOPSIS
use FCM::System::Make::Build::Task::Archive;
my $build_task = FCM::System::Make::Build::Task::Archive->new(\%attrib);
$build_task->main($target);
=head1 DESCRIPTION
Invokes the archive to create the target archive library.
=head1 METHODS
=over 4
=item $class->new(\%attrib)
Creates and returns a new instance. %attrib should contain:
=over 4
=item {prop_of}
A HASH that maps the property names (used by this task) to their default values.
=item {util}
An instance of L<FCM::Util|FCM::Util>.
=back
=item $instance->main($target)
Invokes the "ar" command to create the $target object archive. It uses the
$target->get_info_of('deps')->{o} ARRAY. All "o" dependency items are placed in
the archive.
=item $instance->prop_of()
Returns the HASH that maps the property names (used by this task) to their
default values.
=back
=head1 CONSTANTS
=item %FCM::System::Make::Build::Task::Archive::PROP_OF
A map containing the property names and their default values.
