mac default iconzfec for Mac Publisher's description

A fast erasure codec which can be used with the command-line, C, Python, or Haskell

Fast, portable, programmable erasure coding a.k.a. "forward error correction": the generation of redundant blocks of information such that if some blocks are lost then the original data can be recovered from the remaining blocks.

The zfec pack comes with C API, Python API, Haskell API and command-line tools.

The most widely known example of an erasure code is the RAID-5 algorithm which makes it so that in the event of the loss of any one hard drive, the stored data can be completely recovered.

The algorithm in the zfec package has a similar effect, but instead of recovering from the loss of only a single element, it can be parameterized to choose in advance the number of elements whose loss it can tolerate.

This package is largely based on the old "fec" library by Luigi Rizzo et al., which is a mature and optimized implementation of erasure coding. The zfec package makes several changes from the original "fec" package, including addition of the Python API, refactoring of the C API to support zero-copy operation, a few clean-ups and optimizations of the core code itself, and the addition of a command-line tool named "zfec".
