@section How buttons look like
-Not yet written.
+@vindex mime-use-widget
+Before EMY 1.13.6, you need W- variants of SEMI to show wigdet buttons
+From now on, you only need to set @code{mime-use-widget}
+to @code{t}.
+
+A button is a place where information about a given part is displayed.
+Its contents is already defined.
+
+[You should be able to customize button with format string.
+ This might be implemented in later versions. If you
+ want it, speak up!]
@node Adding Buttons
@section Add button before, after or around an entity
to change content of the button. It must be an alist of type or
type/subtype vs. keywords.
-Three legal keywords are:
+Three valid keywords are:
@table @code
@item before
This means you will have buttons around message/* and
multipart/alternative, and before application/*.
+@node How to deal with broken MUA
+@section Invalid MIME messages
+
+Some MUAs send totally broken MIME messages. According to the standard,
+it's perfectly fine for EMY not to grok those message. However, EMY
+tries to extract as much information as possible. Here's some functions
+that might help you.
+
+Some MUAs localized to Japanese sends these strings as a filename
+parameter of Content-Disposition.
+
+@example
+=?ISO-2022-JP?B?GyRCRnxLXDhsGyhC?=
+@end example
+
+It looks like encoded-words. This usage is strictly prohibited by RFC
+2047. Instead, you should use mechanism described in RFC 2231.
+If you really want to ``decode'' it when saving it to file, you can use
+something like this.
+
+@lisp
+(mime-add-condition
+ 'action
+ '((mode . "extract")
+ (method . mime-save-content-for-broken-message)))
+@end lisp
+
+Unfortunately, there's no easy way to customize looking of buttons.
+It's on EMY's TODO list.
+
+If you are desperate, you can redefine
+@code{mime-view-insert-entity-button}.
+
