=head1 NAME

HTTP::Request::CurlParameters - container for a Curl-like HTTP request

=head1 SYNOPSIS

  my $ua = LWP::UserAgent->new;
  my $params = HTTP::Request::CurlParameters->new(argv => \@ARGV);
  my $response = $ua->request($params->as_request);

=head1 DESCRIPTION

Objects of this class are mostly created from L. Most
likely you want to use that module instead:

  my $ua = LWP::UserAgent->new;
  my $params = HTTP::Request::FromCurl->new(command_curl => $cmd);
  my $response = $ua->request($params->as_request);
