+========================
+Regular expression field
+========================
+
+Let's first create the regex field.
+
+  >>> from z3c.schema.regex import Regex
+  >>> regex = Regex()
+
+The regex field only allows compilable regular expressions.
+
+  >>> regex.validate(r'.*')
+  >>> regex.validate(r'^\s+$')
+
+It does not validate regular expressions that do not compile.
+
+  >>> regex.validate('(i')
+  Traceback (most recent call last):
+  ...
+  InvalidRegex: '(i', unbalanced parenthesis
+
