/*******************************************************
|
|
* 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.
