Description:
MySQL Fabric doesn't provide a common way to get help or version-info.
* no --help nor --version
* no version command
* the help command seems to exist, but gives no user-friendly message
How to repeat:
$ ./mysqlfabric
Usage: %fabric <group> <cmd> [<option> ...] arg ...
mysqlfabric: error: No command was defined.
$ ./mysqlfabric help
Usage: %fabric <group> <cmd> [<option> ...] arg ...
mysqlfabric: error: Error (dispatch() takes exactly 3 arguments (1 given)). Wrong number of parameters were provided for command (manage help).
$ ./mysqlfabric version
Usage: %fabric <group> <cmd> [<option> ...] arg ...
mysqlfabric: error: Wrong syntax.
$ ./mysqlfabric --help
Usage: %fabric <group> <cmd> [<option> ...] arg ...
mysqlfabric: error: Wrong syntax.
$ ./mysqlfabric --version
Usage: %fabric <group> <cmd> [<option> ...] arg ...
mysqlfabric: error: Wrong syntax.
Suggested fix:
provide a way to the user to get help using the format all other unix-utilities use.
