Adding wolfSSL (formerly CyaSSL) support
=====

In order to support SSL *HTTPS* connections in Civetweb,
you may wish to use the GPLv2 licensed CyaSSL library.  By using this
library, the resulting binary may have to have the GPL license unless
you buy a commercial license from [wolfSSL](http://www.yassl.com/).

*Note: The following instructions have not been checked for the most recent versions of CivetWeb and wolfSSL. Some information might be outdated.*
