+Fast GF(256) Cauchy MDS Block Erasure Codec in C++.
+
+This is the rewrite in (as much as possible) clean C++ of cm256.
+
+cm256cc is a simple library for erasure codes. From given data it
+generates redundant data that can be used to recover the originals.
+
+Currently only g++ is supported, other versions of MSVC than Visual
+Studio 2013 may work. Optimizations for both SSE3 (x86_64) and Neon
+(armv7) are available.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
