Attempts to examine the SHELL_FACTORY_OPTION configuration.

• If missing/empty then returns the DEFAULT_SHELL_FACTORY.
• If NONE then returns null
• If SCP then returns a ScpCommandFactory
• Otherwise, assumes this is a fully qualified class path of a ShellFactory implementation and attempts to load and instantiate it using a public no-args constructor

Parameters:

level - The verbosity Level

stdout - The STDOUT stream for logging

stderr - The STDERR stream for errors

options - The available options - assuming defaults if null

Returns:

The resolved ShellFactory

Throws:

Exception - If failed to resolve
