var swap = new CacheSwap({
    cacheDirName: "HoganizeSwap"
  }),
  processTemplate = function(template, done) {
    var templateStr = template.content,
      templatePath = template.path,
      templateHash = files.shaIt(templateStr);

    swap.getCached("hoganize", templateHash, function(err, cached) {
      if(err) {
        return done(err);
      }

      var yeahbrotha,
        stringed;

      if(cached) {
        yeahbrotha = cached.contents;
        try {
          addToHoganized(yeahbrotha, templatePath);
        } catch(e){
          return done(e);
        }

        done();
      } else {
        yeahbrotha = self._compileTemplate(templateStr, templatePath);
        // Add the compiled template to the cache swap for next time.
        swap.addCached("hoganize", templateHash, yeahbrotha, function(err) {
          if(err) {
            return done(err);
          }

          try {
            addToHoganized(yeahbrotha, templatePath);
