The HPACK Multi-System Archiver is an archiver that was written to allow the transfer of archived data to different systems. In the past archivers have traditionally been available for single systems only, for example
PKZip and LHARC for the IBM PC, Larc for the Amiga, StuffIt(tm) and Compactor for the
Macintosh, and tar and compress for UNIX systems (while these archivers are available on other systems, their use is not widespread). It is intended to make HPACK a more universal archiver by offering versions for the following
environments:
Apple IIgs (planned)(?);
Archimedes;
Atari ST;
Commodore Amiga;
Microsoft Windows;
Macintosh;
MSDOS;
OS/2 (16 and 32-bit versions);
OS/2 Presentation Manager (currently in development)(?);
Primos (planned);
UNIX;
VMS (currently in development);
Any other system which people offer to port it to.
