=method new

  my $uploader = CPAN::Uploader->new(\%arg);

This method returns a new uploader.  You probably don't need to worry about
this method.

Valid arguments are the same as those to C<upload_file>.

=cut

sub new {
  my ($class, $arg) = @_;

  $arg->{$_} or Carp::croak("missing $_ argument") for qw(user password);
  bless $arg => $class;
}

=method read_config_file

  my $config = CPAN::Uploader->read_config_file( $filename );

This reads the config file and returns a hashref of its contents that can be
used as configuration for CPAN::Uploader.

If no filename is given, it looks for F<.pause> in the user's home directory
(from the env var C<HOME>, or the current directory if C<HOME> isn't set).

See L<cpan-upload/CONFIGURATION> for the config format.

=cut

sub read_config_file {
  my ($class, $filename) = @_;

  unless (defined $filename) {
    my $home  = File::HomeDir->my_home || '.';
    $filename = File::Spec->catfile($home, '.pause');

    return {} unless -e $filename and -r _;
  }

  my %conf;
  if ( eval { require Config::Identity } ) {
    %conf = Config::Identity->load($filename);
    $conf{user} = delete $conf{username} unless $conf{user};
  }
  else { # Process .pause manually
    open my $pauserc, '<', $filename
      or die "can't open $filename for reading: $!";

    while (<$pauserc>) {
      chomp;
      next unless $_ and $_ !~ /^\s*#/;

      my ($k, $v) = /^\s*(\w+)\s+(.+)$/;
      Carp::croak "multiple enties for $k" if $conf{$k};
      $conf{$k} = $v;
    }
  }

  return \%conf;
}

=method log

  $uploader->log($message);

This method logs the given string.  The default behavior is to print it to the
screen.  The message should not end in a newline, as one will be added as
needed.

  shift;
