+/*******************************************************
+ * This file contains classes and templates that deal
+ * with the comparison and hashing of 'irc strings'.
+ * An 'irc string' is a string which compares in a
+ * case insensitive manner, and as per RFC 1459 will
+ * treat [ identical to {, ] identical to }, and \
+ * as identical to |.
+ *
+ * Our hashing functions are designed to accept
+ * std::string and compare/hash them as type irc::string
+ * by converting them internally. This makes them
+ * backwards compatible with other code which is not
+ * aware of irc::string.
