+    can be called with the following external commands:
+        - node release.js                   returns version of app
+        - node release.js generate          generates uuid / guid and shows all env vars in console
+        - node release.js uuid              returns app uuid
+        - node release.js guid              returns app guid
+        - node release.js versiom           returns version of app
+
+    can be called with the following app commands:
+        - npm run release
+        - npm run release:generate
+        - npm run env-release
+        - npm run env-uuid
