Ant build in subdirectory

[Alex Boisvert]

Howdy,
I have a project where the Ant build file is located in a sub-directory 
with respect to the checkout root.

CheckoutRoot
    |
    +--- subDirectory
           |
           +---- build.xml

Problem is, I need to checkout at CheckoutRoot because there are other 
artifacts that need to be present for the build.

Is there a way to tell Continuum to use subDirectory\build.xml?

Ideally, I would like the following effect when triggering the build:

% (checkout tree using CVS)
% cd subDirectory
% ant build.xml

thanks,
alex
