+     "The binary-layout library allows type-safe, inplace, zero-copy access to
+structured binary data.  You define a custom data layout and give it a slice of
+binary data, and it will allow you to read and write the fields defined in the
+layout from the binary data without having to copy any of the data.  It's
+similar to transmuting to/from a `#[repr(packed)]` struct, but much safer.")
