/**
 * Raspbian WiFi Configuration Portal (RaspAP)
 *
 * Enables use of simple web interface rather than SSH to control wifi and hostapd on the Raspberry Pi.
 * Recommended distribution is Raspbian Buster Lite. Specific instructions to install the supported software are
 * in the README and original post by @SirLagz. For a quick run through, the packages required for the WebGUI are:
 * lighttpd (version 1.4.53 installed via apt)
 * php-cgi (version 7.3.14-1 installed via apt)
 * along with their supporting packages, php7.3 will also need to be enabled.
