paq is a family of archivers with the best lossless compression ratios now
|
|
available across a wide variety of test data, according to several benchmarks.

The port uses the open ZPAQ specification, and contains: a public-domain C++
|
|
API for reading and writing ZPAQ compressed data to or from files or objects
|
|
in memory; serial and multi-threaded archivers; extra preprocessors for
|
|
compression; and stubs for creating self-extracting archives.
