=head1 NAME
Plack::HTTPParser - Parse HTTP headers
=head1 SYNOPSIS
use Plack::HTTPParser qw(parse_http_request);
my $ret = parse_http_request($header_str, \%env);
# see HTTP::Parser::XS docs
=head1 DESCRIPTION
Plack::HTTPParser is a wrapper class to dispatch C<parse_http_request>
to Kazuho Oku's XS based HTTP::Parser::XS or pure perl fallback based
on David Robins HTTP::Parser.
If you want to force the use of the slower pure perl version even if the
fast XS version is available, set the environment variable
C<PLACK_HTTP_PARSER_PP> to 1.
