command.ExecTest & PATH

[Vladimir Prus <ghost@xxxxxxxxx>]

I have a small question:

command.ExecTest expects the program to be given either as absolute path, or 
to be found in PATH. I naturally want to reference the binary in my working 
copy, but so far has no idea how this can be done.
1. Is there a way to reference context variables inside program name? Inside 
parameter list? I'd say this approach to be the best, since I'd like the 
ability to use working-copy relative names in parameters.
2. Is is possible to create a resource that will set PATH accordingly? Will 
that change affect the path where command.ExecTest looks for the binary?

Regards,
Vladimir
