Use "cbt help <command>" for more information about a command.

The options are:

-project string
	project ID, if unset uses gcloud configured project
-instance string
	Cloud Bigtable instance
-creds string
	if set, use application credentials in this file

Alpha features are not currently available to most Cloud Bigtable customers. The features might be changed in backward-incompatible ways and are not recommended for production use. They are not subject to any SLA or deprecation policy.

For convenience, values of the -project, -instance, -creds, -admin-endpoint and -data-endpoint flags may be specified in ~/.cbtrc in this format:

project = my-project-123
instance = my-instance
creds = path-to-account-key.json
admin-endpoint = hostname:port
data-endpoint = hostname:port

All values are optional, and all will be overridden by flags.
