/**
 * LHA (LHarc, LZH) is a file format used by a popular freeware
 * eponymous archiver, created in 1988 by Haruyasu Yoshizaki. Over the
 * years, many ports and implementations were developed, sporting many
 * extensions to original 1988 LZH.
 * 
 * File format is pretty simple and essentially consists of a stream of
 * records.
