"""The installer narrows a platform the way the pack builder does.

|
|
The one-liner can install a chosen set of systems, cores and regions. It runs
|
|
without the profiles or the database, from the manifest alone, so the
|
|
manifest records each file's systems and regional competition and the
|
|
installer replays the builder's region rule. These tests hold the two ends

to one answer.
