 The bin/ directory contains two Unix-style, command-line tools "zfec" and
 "zunfec".  Execute "zfec --help" or "zunfec --help" for usage instructions.
 
-Note: a Unix-style tool like "zfec" does only one thing -- in this case erasure
-coding -- and leaves other tasks to other tools.  Other Unix-style tools that go
-well with zfec include "GNU tar" or "7z" a.k.a. "p7zip" for archiving multiple
-files and directories into one file, "rzip" for compression, and "GNU Privacy
-Guard" for encryption or "sha256sum" for integrity.  It is important to do
-things in order: first archive, then compress, then either encrypt or sha256sum,
-then erasure code.  Note that if GNU Privacy Guard is used for privacy, then it
-will also ensure integrity, so the use of sha256sum is unnecessary in that case.
-Note that if 7z is used for archiving then it also does compression, so you 
-don't need a separate compressor in that case.
