 *
 * Demonstrates the simplest example using the LWS high-level SS apis, doing
 * an h1 GET from warmcat.com.
 *
 * It specifies its own policy and restricts the tls library to validating the
 * certificate through a single trusted CA cert defined in the policy.
 *
 *  - main.c:              (this file) boilerplate to create the lws_context
 *			   and event loop
 *  - hello_world-ss.c:    the secure stream user code
 *  - example-policy.json: the example policy
 *
 * Configure lws with -DCMAKE_BUILD_TYPE=DEBUG to build verbose logs, enable at
 * runtime by giving -d 1039 or -d 1151 on this example commandline.
