USAGE:

EXAMPLES:
1. Create a bucket on Amazon S3 cloud storage.
$ mc {{.Name}} s3/mynewbucket
2. Create a new bucket on Google Cloud Storage.
$ mc {{.Name}} gcs/miniocloud
4. Create a new bucket on Amazon S3 cloud storage in region ‘us-west-2’.
$ mc {{.Name}} --region=us-west-2 s3/myregionbucket
5. Create a new directory including its missing parents (equivalent to ‘mkdir -p’).
$ mc {{.Name}} /tmp/this/new/dir1
6. Create multiple directories including its missing parents (behavior similar to ‘mkdir -p’).
$ mc {{.Name}} /mnt/sdb/mydisk /mnt/sdc/mydisk /mnt/sdd/mydisk
