Initial import of ldpc-20060208 into the Packages Collection.

This collection of programs and modules, written in C, is
intended to support research and education concerning Low
Density Parity Check (LDPC) codes.  (Note, however, that the
copyright notice no longer restricts use to these purposes).
These codes were invented by Robert Gallager in the early
1960's, and re-invented and shown to have very good
performance by David MacKay and myself in the mid-1990's.  The
decoding algorithm for LDPC codes is related to that used for
Turbo codes, and to probabilistic inference methods used in
other fields.  Variations on LDPC and Turbo codes are
currently the best practical codes known, in terms of their
ability to transmit data at rates approaching channel capacity
with very low error probability.
