Noe is a tool that generates project skeletons from predefined templates. A template is designed for a specific product (a ruby library, a static or dynamic web site, ...). Noe instantiates templates and helps you maintaining your product via meta-information provided by a .noespec yaml file. In contrast to other tools, Noe is not specific to certain kinds of products. Even if Noe comes bundled with a default template to develop gem libraries, writing your own template is possible and even simple!
