How can I specify a location to write the code coverage files generated with '-cov'?

[Saurabh Das]

Hello,

Say I compile a program with:
dmd -unittest -debug -cov test.d

Then, when I run ./test, a file 'test.lst' is generated in the 
current working directory. Is there a way in which I can instruct 
the file to be created in a separate './cov_log/' directory?

Thanks,
Saurabh
