Main function declaration for confab console_script.
Confab may be used from within a fabfile or as a library. The main function here is provided as a simple default way to invoke confab’s tasks:
- A single directory root is assumed, with templates, data, generated and remotes directories defined as subdirectories.
- A host list must be provided on the command line.
For more complex invocation, a custom fabfile may be more appropriate.
