+  Configuration options can be included using the "include" directive.
+  Include takes a list of files to include. Quoting and wildcards is
+  supported.
+
+  For example,
+
+  include /path/to/included/file/squid.acl.config
+
+  Includes can be nested up to a hard-coded depth of 16 levels.
+  This arbitrary restriction is to prevent recursive include references
+  from causing Squid entering an infinite loop whilst trying to load
+  configuration files.
