+* changed points of tm-view
+
+  Internal structure of tm-view 6.* is changed from tm-view 5.21, such 
+as, data structures, symbol names. I write main differences between tm 
+5.21.
+
+** internal structure
+
+*** content-info
+
+  Buffer local variable of article buffer `mime/content-list', which
+memorizes content structres of message in article buffer, is renamed
+to `mime::article/content-info', and data structure is changed.
+
+  Old data structure ``content-list'' used in buffer local variable
+`mime/content-list' was a following list:
+
+	content-list = (Ba Ea children)
+
+		Ba: point-min of this content in article buffer
+		Ea: point-max of this content in article buffer
+		children: content-list's list of contents included in
+			  this content. nil when this content is not
+			  multipart
+
+
+  New data structure ``content-info'' used in buffer local variable
+`mime::article/content-info' is following vector:
+
+	content-info
+	 = [point-min point-max type parameters encoding children]
+
+		point-min:  point-min of this content in article buffer
+		point-max:  point-max of this content in article buffer
+			    (This value is not equal Ea.
+			     point-max = Ea + 1)
+		type:       content-type/subtype of this content
+		parameters: assoc-list which represents parameters of
+			    Content-Type field of this content
+		encoding:   Content-Transfer-Encoding of this content
+		children:   content-info's list of contents included
+		            in this content. nil when this content is
+			    not multipart
+
+
+  In tm-view 5.21, this data structure was generated and referenced by
+list processing functions (basic lisp functions) dynamically. In
+tm-view 6.*, however, it is generated by generator function
+`mime::make-content-info', and it is referenced by reference functions
+mime::content-info/FOO (FOO = { point-min | point-max | type |
+parameters | encoding | children }).
+
+
+*** preview-content-info
+
+  Buffer local variable of preview buffer
+`mime/preview-flat-content-list', which memorizes content structres of
+message in preview buffer, is renamed to `mime::preview/content-list,
+and data structure is changed.
+
+  Old data structure used in buffer local variable
+`mime/preview-flat-content-list' was a list which elements are
+following list:
+
+	(Bp Ep buf Ba Ea)
+
+		Bp: point-min of this content in preview buffer
+		Ep: point-max of this content in preview buffer
+		buf: article buffer for this content
+		Ba: point-min of this content in article buffer
+		Ea: point-max of this content in article buffer
+
+
+  New data structure ``preview-content-info'' used in buffer local
+variable `mime::preview/content-list'' is a list which elements are
+following vector:
+
+	[Bp Ep buf cinfo]
+
+		Bp: point-min of this content in preview buffer
+		Ep: point-max of this content in preview buffer
+		buf: article buffer for this content
+		cinfo: content-info which represents this content
+
+
+  In tm-view 5.21, this data structure was generated and referenced by
+list processing functions (basic lisp functions) dynamically. In
+tm-view 6.*, however, it is generated by generator function
+`mime::make-preview-content-info', and it is referenced by reference
+functions mime::preview-content-info/FOO (FOO = { Bp | Ep | buf |
+cinfo }).
+
+
+*** etc
+
+- parser is changed
+
+- naming rule is changed
+
+- buffer local variable in article buffer `mime/preview-buffer' is
+  renamed to `mime::article/preview-buffer'
+
+- function `mime/exit-view-mode' is renamed to `mime-viewer/kill-buffer'
+
+- command functions of mime/viewer-mode are renamed from mime/FOO to
+  mime-viewer/FOO. (ex. `mime/up-content' --> `mime-viewer/up-content')
+
+- command function `mime/quit-view-mode' is renamed to `mime-viewer/quit'
+
+- etc...
+
+
+** variables
+
+(1) variable `mime/content-filter-alist' is renamed to
+    `mime-viewer/content-filter-alist'
+
+(2) variable `mime/make-content-subject-function' is renamed to
+    `mime-viewer/content-subject-function' and arguments are changed
+
+(3) variable `mime/make-content-header-filter' is renamed to
+    `mime-viewer/content-header-filter-function'
+
+(4) variable `mime/default-showing-Content-Type-list' is renamed to
+    `mime-viewer/default-showing-Content-Type-list'
+
+(5) variable `mime/go-to-top-node-method-alist' is renamed to
+    `mime-viewer/quitting-method-alist' and changed initial value
+    because of changes between tm-view 5.21 and tm-view 6.*.

+* tm-view の変更点について
+
+  tm-view 6.* では内部構造が変更され、データ構造や symbol 名などが変更
+されています。以下では、tm-view 5.21 からの主な変更点を挙げます。
+
+** 内部構造の変更
+
+*** content-info
+
+  article buffer において、message に含まれる content の構造を記憶する 
+buffer local 変数 mime/content-list を mime::article/content-info に改
+名し、データ構造を変更した。具体的には、従来、
+
+	content-list = (Ba Ea Children)
+
+	但し、
+		Ba: article buffer でのこの content の先頭 point
+		Ea: article buffer でのこの content の末尾 point
+		Children: この content に含まれる content の情報。
+			  content-list を要素とする list で表し、
+			  multipart の content でない場合は nil が入る
+
+という list で表現していたのを、
+
+	content-info
+	 = [point-min point-max type parameters encoding children]
+
+	但し、
+		point-min: article buffer でのこの content の先頭 
+			   point
+		point-max: article buffer でのこの content の末尾 
+			   point（Ea とは異なり、point-min と 
+			   point-max で作られる region がその content 
+			   になるようになっている。point-max = Ea + 1 
+			   の関係が成り立つ）
+		type:       この content の content-type/subtype
+		parameters: この content の Content-Type field の 
+			    paraeter を表す連想リスト
+		encoding:   この content の Content-Transfer-Encoding.
+		children: この content に含まれる content の情報。
+			  content-info を要素とする list で表し、
+			  multipart の content でない場合は nil が入る
+
+という vector で表現するようにした。
+
+  また、従来、list 処理関数を使って直接 list を生成・参照していたのを、
+生成関数 mime::make-content-info, 参照関数 mime::content-info/FOO (FOO
+= {point-min|point-max|type|parameters|encoding|children}) を使うよう
+にした。
+
+  また、従来、Content-Type, Content-Transfer-Encoding field の情報をい
+ちいち buffer を検索して求めていたのを、content-info を参照するように
+した。
+
+*** preview-content-info
+
+  preview buffer において、message に含まれる content の構造を記憶する 
+buffer local 変数 mime/preview-flat-content-list を
+mime::preview/content-list に改名し、データ構造を変更した。具体的には、
+従来、
+
+	(Bp Ep buf Ba Ea)
+
+	但し、
+		Bp: preview buffer でのこの content の先頭 point
+		Ep: preview buffer でのこの content の末尾 point
+		buf: この content に対応する article buffer
+		Ba: article buffer でのこの content の先頭 point
+		Ea: article buffer でのこの content の末尾 point
+
+という list で表現していたのを、
+
+	[Bp Ep buf cinfo]
+
+	但し、
+		Bp: preview buffer でのこの content の先頭 point
+		Ep: preview buffer でのこの content の末尾 point
+		buf: この content に対応する article buffer
+		cinfo: この content を表す content-info
+
+という vector で表現するようにした。
+
+  また、従来、list 処理関数を使って直接 list を生成・参照していたのを、
+生成関数 mime::make-preview-content-info, 参照関数 
+mime::preview-content-info/FOO (FOO = {Bp|Ep|buf|cinfo}) を使うように
+した。
+
+
+*** その他
+
+・parser を変更した
+
+・命名規則を変更した
+
+・article buffer の buffer local 変数 mime/preview-buffer を 
+  mime::article/preview-buffer に改名した。
+
+・関数 mime/exit-view-mode を mime-viewer/kill-buffer に改名した。
+
+・mime/viewer-mode の各関数を mime/FOO から mime-viewer/FOO に改名した。
+  （例：mime/up-content → mime-viewer/up-content）
+
+・関数 mime/quit-view-mode を mime-viewer/quit に改名した。
+
+・その他
+
+
+** 主な変数名の変更
+
+(1) 変数 mime/content-filter-alist を mime-viewer/content-filter-alist
+    に改名した。
+
+(2) 変数 mime/make-content-subject-function を
+    mime-viewer/content-subject-function に改名し、引数を変更した。
+
+(3) 変数 mime/make-content-header-filter を
+    mime-viewer/content-header-filter-function に改名した。
+
+(4) 変数 mime/default-showing-Content-Type-list を
+    mime-viewer/default-showing-Content-Type-list に改名した。
+
+(5) 変数 mime/go-to-top-node-method-alist を
+    mime-viewer/quitting-method-alist に改名した。また、symbol 名や仕
+    様の変更にともない、初期設定を変更した。
