Don't invoke target X if output file is "current"

[John Lindwall <JL...@Xifin.com>]

I'm missing a feature from make.  How can I avoid invoking a target if the "output file" is "current" (ie newer then the "input file")?

In ant it seems that this kind of dependency checking is left to the task implementation.  Do I have to create a custom task every time I want to implement this kind of checking?  DependSet does not seem to be what I want.  

Thanks!

In general, yes.
