=head1 NAME

spdy-server - Example Net::SPDY server

=head1 ALPHA WARNING

B<Please read carefully:> This is an ALPHA stage software.
In particular this means that even though it probably won't kill your cat,
re-elect George W. Bush nor install Solaris 11 Express edition to your hard
drive, it is in active development, functionality is missing and no APIs are
stable.

See F<TODO> file in the distribution to learn about missing and planned
functionality. You are more than welcome to join the development and submit
patches with fixes or enhancements.  Bug reports are probably not very useful
at this point.

=head1 SYNOPSIS

spdy-server <listen-uri> <ssl-certificate> <ssl-certificate-key>

=head1 DESCRIPTION

B<spdy-server> is a toy SPDY web server, showcasing L<Net::SPDY>
capabilities.

It's hardly of any useful use.
