%description
WStunnel creates an HTTPS tunnel that can connect servers sitting behind an HTTP
proxy and firewall to clients on the internet. It differs from many other
projects by handling many concurrent tunnels allowing a central client (or set
of clients) to make requests to many servers sitting behind firewalls. Each
client/server pair are joined through a rendez-vous token
