Except from the Yeoman template [generator-couchapp](https://github.com/garbados/generator-couchapp) that recursively copies everything in the template directory accordingly to some simple rules. Cheap time-saver.

gistfile1.js

CouchappGenerator.prototype.app = function app() {
  // copy everything in `templates` based on rules:
  // - if dir, this.directory
  // - if filename starts with '__', ignore
  // - if filename starts with '_', this.template
  // - else, this.copy
  var files = fs.readdirSync(__dirname + "/templates");
  for(var i in files){
    var stat = fs.statSync(__dirname + "/templates/" + files[i]);
    if(stat.isDirectory()){
      this.directory(files[i]);
    }else{
      if(files[i][0] === '_'){
        if(files[i][1] === '_'){
          // ignore the file; allow later directives to handle it
        }else{
          this.template(files[i], files[i].slice(1));
        }
      }else{
        this.copy(files[i], files[i]);
      }
    }
  }
};
