-Release:
-  - Concatenates autostart modules, application modules' module.json descriptors,
-    and the application loader into a single script.
-  - Builds app.html referencing the application script.
-Debug:
-  - Copies the module directories into their destinations.
-  - Copies app.html as-is.
+Builds applications in release mode:
+- Concatenates autostart modules, application modules' module.json descriptors,
+and the application loader into a single script.
+- Builds app.html referencing the application script.
