Not exactly. Yours is a bit different:

   Foo in 'whereever/the/lcl/dir/is' as FooLCL,
   Foo in 'whereever/the/rtl/dir/is' as FooRTL;

The idea of Martin's concept is to define "aliases" for the search paths 
as well so that you can change them by configuration or command line. So 
you wouldn't need to check whether your path to the e.g. the LCL is the 
same as on Martin's computer or mine.

Whether we use "as" or "alias" and a string or an identifier for the 
unit alias is not that an important topic.
