Usage: $basename [-d] [-b=NNN] [-h] [-p proxy_name:port] [-CAfile=FILE] [GET|HEAD] [ssl_server_name] [port]

  -d  Debug mode
  -b  Benchmark NNN times, good test for memory leaks
  -h  This help message
  -p  Proxy server, via CONNECT method, localhost:80 format

  -cert  client certificate file
  -key   private key file

  -CAfile CA certificates file, use certs/ca-bundle.crt for primary root certs

 method          defaults to HEAD
 ssl_server_name defaults to www.nodeworks.com
 port            defaults to 443

These are equivalent:

  ./net_ssl_test
  ./net_ssl_test HEAD www.nodeworks.com 443

This might be how you debug your proxy:

  ./net_ssl_test -d -p http://proxy_name:80 www.nodeworks.com

Note http:// on proxy hostname is stripped off, and is
meaningless to Crypt::SSLeay.
