+##########
+# Fields #
+##########
+
+Each Field class does some sort of validation. Each Field has a clean() method,
+which either raises django.newforms.ValidationError or returns the "clean"
+data -- usually a Unicode object, but, in some rare cases, a list.
+
+Each Field's __init__() takes at least these parameters:
+    required -- Boolean that specifies whether the field is required.
+                True by default.
+    widget -- A Widget class, or instance of a Widget class, that should be
+              used for this Field when displaying it. Each Field has a default
+              Widget that it'll use if you don't specify this. In most cases,
+              the default widget is TextInput.
+    label -- A verbose name for this field, for use in displaying this field in
+             a form. By default, Django will use a "pretty" version of the form
+             field name, if the Field is part of a Form.
+    initial -- A value to use in this Field's initial display. This value is
+               *not* used as a fallback if data isn't given.
+
+Other than that, the Field subclasses have class-specific options for
+__init__(). For example, CharField has a max_length option.
