Dirk, Thanks for the response.
However that's not quite what I'm looking for.
Perhaps it was not well illustrated by my simple example.
Let say my build also contained a build of a program bar, I don't want my
installation directory to be deleted just because I tried to build bar.
If however I delete foo.txt from my build and then I run the install
target, I don't want to see foo.txt in the install directory.

So I actually do want the delete target to be a dependency of any of the
install targets. I'm just not sure how to achieve that.

Regards,
Pico
