Folderize
Folderize is a quick and easy way to get set up with a Ruby file strucutre. To install type the following into your Terminal:
$ gem install folderize
Once installed and you want to create a new Ruby project, create a new directory for your project and run the following command at the root of your new project:
$ folderize
After a few moments, you should have a fully-scaffolded Ruby file directory to start working with.
Notes
The generator is very beta at the moment. The project is licensed under MIT so use at your own risk. Any pull requests to add new functionality are welcome!
