I don't have source available, but I seem to recall that the term "relative URI"
is used elsewhere in dartc to mean "relative to the current working directory".
Perhaps "getDartURI" would be less subject to confusion.

[danrubel, 2012/05/16 04:26:36]

"getDartUri" would be a better name given it's current implementation, but we
are enhancing this method, the "tranlateUri" method, and the "expandUri" method
to support the "package:" URI scheme. If you have a better name that does not
include the word "dart" ...

[Brian Wilkerson, 2012/05/14 14:19:58]

This implies that libraries outside the SDK *should* be converted, but it isn't
clear to me why they should be.

[danrubel, 2012/05/16 04:26:36]

Agreed.

The "config" can be modified to point to something outside the dart-sdk
directory, and there is a request to support "dart:" libraries under development
outside the dart-sdk/lib directory ... thus the comment that this method
implementation could be enhanced in the future.

nit: seems like there must be a constant for this somewhere
