def usage



  "\nNote: If exactly one argument is given the CLI assumes it is a connection string.
  \n#{'='*80}\n= Examples\n#{'='*80}

  1. Use a connection string to connect to the database

    $ dm mysql://root@localhost/test_development

    Notes: The connection string has the format:

      adapter://user:password@host:port/database

    Where adapter is in: {mysql, pgsql, sqlite...}

  2. Load the database by specifying only cli options

    $ dm -a mysql -u root -h localhost -d test_development -e developemnt


  3. Load the database using a yaml config file and specifying the environment to use

    $ dm --yaml config/database.yml -e development


  4. Load everything from a config file, this example is equivalent to the above

    $ dm --config config/development.yml


  5. Load the database and some model files from a directory, specifying the environment

    $ dm --yaml config/database.yml -e development --models app/models


  6. Load an assumed structure of a typical merb application

    $ dm --merb -e development

  Note: This is similar to merb -i without the merb framework being loaded.
