;; LZH A series of (header,file). Headers are checksummed. No
;; interaction among members.
+;; Headers come in three flavours called level 0, 1 and 2 headers.
+;; Level 2 header is free of DOS specific restrictions and most
+;; prevalently used. Also level 1 and 2 headers consist of base
+;; and extension headers. For more details see
+;; http://homepage1.nifty.com/dangan/en/Content/Program/Java/jLHA/Notes/Notes.html
+;; http://www.osirusoft.com/joejared/lzhformat.html
;;
;; ZIP A series of (lheader,fil) followed by a "central directory"
;; which is a series of (cheader) followed by an end-of-
;; Each member header points to the next. The archive is
;; terminated by a bogus header with a zero next link.
