Yes, the test stream is a nice class, but when you specify the pattern 
file, the file will be located in the current folder.  When I use jam, 
the current folder will be the project root.  This is not where the 
pattern file belongs, it belongs in the same folder as the test code.  

Putting the relativ path to the pattern file in the code for the test 
program itself is not very csatisfying, so you seem to have more or 
less the same type of problem that I had.

My problem is therefore still unsolved.  In its most basic sense, the 
problem is this: How can I make a jam rule know which folder the 
target's subproject is located in?  Ideally, I would like know how to 
assign this folder to a variable inside the rule actions, so that the 
actions can reference files inside this folder.
