[Lazarus] Strange dependency of units

Why isn't this simply added to the source files (compiler switches)? It 
would be much easier, rock solid and would even allow different settings 
for each unit. No need for a complicated construct like packages.

Realy? I think I have to somehow tell Lazarus about a new package, don't 
I? So what is the advantage to clicking on "Load package" or whatever 
and specifying the location path of the package over copying the units 
into the directory where Lazarus expect them?

I don't see this. When I rename a directory which Lazarus uses then I 
think it will fail. So in the end I need to tell Lararus about the 
change anyway. I have to find out how and where to do this. What is the 
difference to knowing where to specify search paths and change them?

That's the concept of units. I just wonder why this is/was not enough.
