I think I figured out how to make this work, but I don't think it's the
intended usage.
If I set TUSCANY_SCACPP_SYSTEM_ROOT to:
"~/tuscany/services/serviceA:~/tuscany/services/serviceB"
And leave TUSCANY_SCACPP_SYSTEM_PATH blank, then I get all of the
services loaded. Its not loaded as intended though, since what it does
is populate the SCARuntime::system composite with the system composites
from serviceA and serviceB. Does that seem correct?

Subject: RE: [TuscanySCA CPP] problems trying to load services from
multiple directories at once
I have since updated the JIRA with a clarification of what I am trying
to do and have included it here in <JIRA update> tags.
<JIRA update>
Just to clarify one piece of information about this problem:
serviceA and serviceB are totally unrelated. The system composites are
located as follows:
~/tuscany/services/
|
+----->serviceA/serviceA.composite
|
+----->serviceB/serviceB.composite
</JIRA update>
Seems like the problem is that the SCARuntime was designed towards just
having one service loaded at a time. And what I am trying to do is to be
able to load several unrelated services.

I think that them intent is for any composites under the
TUSCANY_SCACPP_SYSTEM_ROOT to be loaded so I think it may be an error to
specify a _PATH that includes or is a subdirectory of the SYSTEM_ROOT.
Maybe we could police this or change the loader to ignore duplicates
from the same location.??
