LHA

LHA is the second version of LHARC for DOS.  The LHA format is supported
on the Amiga in the form of the "-lh5-" compression modes supported by LZ,
LX, and LhA.

Most popular compression programs in use today were originally based on the
source code or ideas of "AR002" (an LHA compatible program), although most
programs have advanced since then.
