"""

Runs an application in a manner that allows it to discover various engine
|
||
|
|
resources that may be in unexpected locations.
|
||
|

|
|
In particular: this allows running an application 'in-tree' under a debugger
|
||
|
|
with dependencies and resources out of line.
|
||
|
|

|
The base assumption is that this is probably a special circumstance and hence
|

|
|
should be run reasonably verbose but not interfere with a probable debugger
|

session.
