It defines a "character class". Eg:
matches any digit. You could think of it as (0|1|2|3|4|5|6|7|8|9).
matches c, f, i or l. You can append a quantifier like * or + just as you can with any other character.
A caret at the beginning of a character class negates the whole thing. Thus:
will not match a, b, c or d.
