 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" for archiving multiple files
-and directories into one file, "rzip" or "lrzip" 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.
