This library provides a simple interface to the glibc strfry
function, addressing the perennial programming quandary: "How do I
take good data in string form and painlessly turn it into garbage?"
For more information, consult the glibc documentation:
http://www.gnu.org/software/libc/manual/html_node/strfry.html
Both String and ByteString interfaces are offered, as well as
the raw FFI binding.
