+ * Simple LD_PRELOAD wrapper for connect() which uses tlsproxy as proxy for
+ * programs which don't support setting a TLS proxy.
+ *
+ * The following environment variables can be used:
+ *
+ * - TLSPROXYHELPER_PORT: port where tlsproxy is running (default 9000)
+ *
+ * If an error occurs -1 is returned and errno is set (either EAFNOSUPPORT if
+ * another protocol besides IPv4/IPv6 was used, or EINVAL if another error
+ * occurred). The error is written to stderr with "tlsproxyhelper:" as prefix.
