This is v0.10 of PyECLib. This library provides a simple Python interface for
implementing erasure codes and is known to work with Python v2.6, 2.7 and 3.x.
To obtain the best possible performance, the underlying erasure code algorithms
are written in C. Please let us know if you have any other issues building or
installing (email: kmgreen2@gmail.com or tusharsg@gmail.com).
To obtain the best possible performance, the library utilizes liberasurecode,
which is a C based erasure code library. Please let us know if you have any
other issues building or installing (email: kmgreen2@gmail.com or
tusharsg@gmail.com).
This library makes use of Jerasure for Reed-Solomon and provides its own flat
XOR-based erasure code encoder and decoder. Currently, it implements a
specific class of HD Combination Codes (see "Flat XOR-based erasure codes in
storage systems: Constructions, efficient recovery, and tradeoffs" in IEEE MSST
2010). These codes are well-suited to archival use-cases, have a simple
construction and require a minimum number of participating disks during
single-disk reconstruction (think XOR-based LRC code).

This package includes *c_eclib*, which contains a few C libraries used by
PyECLib. These are built when running the PyECLib install (see below).
As mentioned above, PyECLib depends on the installation of the liberasurecde library (liberasurecode
