// This library allows to check for "bad words". Users cannot login or create a room with such words,
// in messages they are replaced by the "@#$*!" string or the one you choose.

	// function is called to find them in strings, you may use valid POSIX 1003.2 regular expressions
	// (see second line of the array for an example).
	// Note that search is not case sensitive, except for special characters such as accentued ones.
