[Thomas:
 - include Config.in file directly from package/Config.in and not from
   package/nginx/Config.
 - improve Config.in help text with more details
 - rename the package prompt from ngx_http_naxsi_module to nginx-naxsi
 - remove NGINX_NAXSI_SOURCE, and fix the definition of
   NGINX_NAXSI_SITE
 - change license from GPLv3 to GPLv2+ with OpenSSL exception
 - cange license file from LICENSE to naxsi_src/naxsi_json.c. The
   LICENSE file exists in the latest Git master of the project, but
   not in the 0.54 tag that we're packaging.]

+
+         Technically, it is a third party nginx module, available as
+         a package for many UNIX-like platforms. This module, by
+         default, reads a small subset of simple (and readable) rules
+         containing 99% of known patterns involved in website
+         vulnerabilities. For example, <, | or drop are not supposed
+         to be part of a URI.
+
+         Being very simple, those patterns may match legitimate
+         queries, it is the Naxsi's administrator duty to add
+         specific rules that will whitelist legitimate
+         behaviours. The administrator can either add whitelists
+         manually by analyzing nginx's error log, or (recommended)
+         start the project with an intensive auto-learning phase that
+         will automatically generate whitelisting rules regarding a
+         website's behaviour.
+
+         In short, Naxsi behaves like a DROP-by-default firewall, the
+         only task is to add required ACCEPT rules for the target
+         website to work properly.
