# cobra init --help
Initialize (cobra init) will create a new application, with a license
and the appropriate structure for a Cobra-based CLI application.

  * If a name is provided, it will be created in the current directory;
  * If no name is provided, the current directory will be assumed;
  * If a relative path is provided, it will be created inside $GOPATH
    (e.g. github.com/spf13/hugo);
  * If an absolute path is provided, it will be created;
  * If the directory already exists but is empty, it will be used.

Init will not use an existing directory with contents.
