The way to stop the application would be

application:stop(entry_app).

(or whatever the actual application is called, if it`s not
`entry_app`)

The application controller will call the entry_app:stop/1
function to allow for e.g. some cleanup procedures to
execute.

Similarly, you use application:start(entry_app) to start the
application. Depending on what you want to see happen if an
application crashes, you could use either

application:start(entry_app, permanent)

(which means the node will terminate if your application
crashes)

or

application:start(entry_app, temporary)

(which means the node will stay up.)

In the entry_app.app file, you need to insert a `mod`
attribute like so:

{mod, {entry_app, []}}

([] will work fine, since your entry_app module doesn`t care
about the args anyway.)
