-This library makes use of Jerasure for Reed-Solomon as implemented by the
-liberasurecode library 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).
+PyECLib supports a variety of Erasure Coding backends including the standard Reed
+Soloman implementations provided by Jerasure [2], liberasurecode [3] and Intel
+ISA-L [4]. It also provides support for a flat XOR-based encoder and decoder

+XOR-based erasure codes in storage systems: Constructions, efficient recovery,
