github.com/martinohmann/skeleton-go (go): Package skeleton provides a CLI tool for bootstrapping projects from skeleton directories. The skeletons can contain any kind of file and special *.skel files which will be evaluated using the golang template engine.  The tool was initial meant for bootstrapping golang projects, but it is actually language agnostic as the skeletons do not need to be golang specific.
