[Haskell-cafe] How do I use ByteString?

Hi all,

I've never found an easy way to deal with ByteStrings.

I'm using the RSA library and it en- and decodes 

I initially start with Strings, ie. [Char], but there is no function to 
convert the 2 back and forth. There is however a function which takes 
[Word8] to BytesString and back.

It all wouldn't be so confusing if there weren't several versions of 
ByteString in several modules to choose from. And a number of libraries 
requiring different types of ByteString.

I am sure the designers of the bytestring package had good reason for 
this design, is there also a webpage which explains which one to use and 
under what circumstances?
