exit codes

fab follows these conventions regarding exit codes.

• 0: Command completed successfully
• 1: Command failed for any reason
• 2: Command was cancelled or there was a misuse of shell builtins (e.g., missing keyword, syntax error)
• 4: Command requires authentication

Note: It is possible that a particular command may have more exit codes, so it is a good practice to check documentation for the command if you are relying on exit codes to control some behavior.
