| This code, based on zfec by Zooko, based on code by Luigi
Rizzo implements an erasure code, or forward error
correction code. 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.
