Getting the public key and token from a strong-name key

I hope we're all familiar with sn -Tp to get the public key details from an assembly -- here using an example where the key is public and anyone can reproduce the results:

>sn -Tp .\Mono.Cecil.dll

Microsoft (R) .NET Framework Strong Name Utility  Version 3.5.30729.1

Public key is
002400000480000094000000060200000024000052534131000400000100010079159977d2d03a

Public key token is 0738eb9f132ed756

But if you haven't built anything yet, you might still want these values from a string-name key pair (e.g. to put in an InternalsVisibleTo attribute on the first assembly at the bottom of the calling stack for the unit tests that are to come). So here's how

so now we can do

>& 'C:\Program Files\FSharp-2.0.0.0\bin\fsi.exe' .\sntp.fsx .\mono.snk
Public key is
002400000480000094000000060200000024000052534131000400000100010079159977d2d03a

and get the values we want. As most of the time you'll want the public key as a continuous string, much of the format nonsense in the script can be dispensed with.
