+/* (alfons) - Just a quick note of how this filtering module works on 
+ * new (arriving) messages.
+ * 
+ * 1) as an initialization step, code in inc.c and mbox.c set up the 
+ *    drop folder to the inbox (see inc.c and mbox.c).
+ *
+ * 2) the message is actually being copied to the drop folder using
+ *    folder_item_add_msg(dropfolder, file, TRUE). this function
+ *    eventually calls mh->add_msg(). however, the important thing
+ *    about this function is, is that the folder is not yet updated
+ *    to reflect the copy. i don't know about the validity of this
+ *    assumption, however, the filtering code assumes this and
+ *    updates the marks itself.
+ *
+ * 3) technically there's nothing wrong with the matcher (the 
+ *    piece of code which matches search strings). there's
+ *    one gotcha in procmsg.c:procmsg_get_message_file(): it
+ *    only reads a message file based on a MsgInfo. for design
+ *    reasons the filtering system should read directly from
+ *    a file (based on the file's name).
+ *
+ * 4) after the matcher sorts out any matches, it looks at the
+ *    action. this part again pushes the folder system design
+ *    to its limits. based on the assumption in 2), the matcher
+ *    knows the message has not been added to the folder system yet.
+ *    it can happily update mark files, and in fact it does.
  * 
- * filter_message() is no longer the entry point for filtering. it's
- * replaced with filter_incoming_message() which does not trust
- * on MsgInfo's from a folder. instead it directly works with
- * the temporary file.  
- * updating the mark file is a lot easier now, because we can do that
- * right after a call to folder_item_add_msg().
