I think the internet browser is an example.

Essentially, he doesn't, because the libraries are not installed. The build
process looks in the temporary cache for the files, and uses them if they're
there, otherwise it downloads them off the network and puts them in the
temporary cache. They are never actually installed.

No, it will not, unless the files happen to already be in the cache. The builder
will look in the cache first for the files.

If that is desired, then they can be actually installed by the administrator.

Being a cache, the least recently used library can always be kicked out, and
then reloaded as necessary. Think of it working like the temporary cache for

These problems are all sidestepped because the libraries won't be installed.
It's a wholly different way of doing things.
