+    // MIME does define a set of general rules for how mail clients should
+    // interpret this tree structure of MIME parts. The Content-Disposition
+    // header is meant to provide hints to the receiving client as to which
+    // parts are meant to be displayed as part of the message body and which
+    // are meant to be interpreted as attachments.
+    //
+    // The Content-Disposition header will generally have one of two values:
+    // inline or attachment.
+
+    // The meaning of these value should be fairly obvious. If the value
+    // is attachment, then the content of said MIME part is meant to be
+    // presented as a file attachment separate from the core message.
+    // However, if the value is inline, then the content of that MIME part
+    // is meant to be displayed inline within the mail client's rendering
+    // of the core message body.
+    //
+    // If the Content-Disposition header does not exist, then it should be
+    // treated as if the value were inline.
+    //
+    // Technically, every part that lacks a Content-Disposition header or
+    // that is marked as inline, then, is part of the core message body.
+    //
+    // There's a bit more to it than that, though.
+    //
+    // Modern MIME messages will often contain a multipart/alternative MIME
+    // container which will generally contain a text/plain and text/html
+    // version of the text that the sender wrote. The text/html version
+    // is typically formatted much closer to what the sender saw in his or
+    // her WYSIWYG editor than the text/plain version.
+    //
+    // Example without multipart/related:
+    // multipart/alternative
+    //  text/plain
+    //  text/html
+    //
