identifying frontend

In some packages, we write something as

put('mypackage, 1, 'version) $

Later, when we want to know if 'mypackage was loaded, we call funtion 
'get. For example, if we don't want to re-load a package  which was 
already loaded:

if not get('mypackage,'version) then load("mypackage") $
