The purpose of libmspack is to provide compressors and decompressors,
archivers and dearchivers for Microsoft compression formats: CAB, CHM,
HLP, KWAJ, LIT and SZDD. It is also designed to be easily embeddable,
stable, robust and resource-efficient.

The library is not intended as a generalised "any archiver" interface.
Users of the library must explicitly choose the format they intend to work
with.

All special features of the above formats will be covered as fully as
possible -- for example, CAB's multi-part cabinet sets, or CHM's fast
lookup indices. All compression methods used by the formats will be
implemented as completely as possible.

However, other than what is required for access to these formats and their
features, no other functionality is intended. There is no file metadata
translation functionality. All file I/O is abstracted, although a default
implementation using the standard C library is provided.
