Re: [ANN] scrypt command-line utility and library

I would start by adding it as optional with a command-line switch. But 
i'm not convinced of it being the optimum default format.

- Password and salt length size restrictions
- Does not use the usual base64 algorithm but a traditional\historical 
one (But it seems only the two special characters differ)
- Uses, and seems to redundantly prefix, the cryptic dollar sign for 
field delimiting

I like the idea of of offering base64 encoding for compatibilty reasons.

For now i wouldn't want to go further than LGPL because i don't want to 
lose copyleft. Most parts of the sourcecode have other licenses anyway.
