=head1 NAME

HTTP::CookieJar::LWP - LWP adapter for HTTP::CookieJar

=head1 VERSION

version 0.014

=head1 SYNOPSIS

  use LWP::UserAgent;
  use HTTP::CookieJar::LWP;

  my $ua = LWP::UserAgent->new(
    cookie_jar => HTTP::CookieJar::LWP->new
  );

=head1 DESCRIPTION

This module is an experimental adapter to make L<HTTP::CookieJar> work with
L<LWP>.  It implements the two methods that C<LWP> calls from L<HTTP::Cookies>.

It is not a general-purpose drop-in replacement for C<HTTP::Cookies> in any
other way.
