+@subsubsection content-body
+@cindex content-body
+
+Content-body represents content of the message. tm-view does not
+display raw content body. For example, if a content has binary, it is
+hidden. If a content has richtext, it is formated. Namely content body
+is hidden or formated.
+
+Function @code{mime-viewer/body-visible-p} is a judge function whether
+content-body of a content is displayed. If it returns @code{nil},
+content-body is hidden. In default, it returns non-@code{nil} when
+content-type of a content is a member of variable
+@code{mime-viewer/default-showing-Content-Type-list}.
+
+When content-body of a content is displayed, content-body is formated
+by content-filter. Content-filter is searched from variable
+@code{mime-viewer/content-filter-alist}. At this time, major-mode of
+the article buffer is used as the key.
+
+If it is not found, function @code{mime-viewer/default-content-filter}
+is called.
+
+
+@defvar mime-viewer/default-showing-Content-Type-list

+you can specify it as argument @var{ctype}.
