Hello Mark,

what you can do is run your cvs update using the exec task and use a 
nested filterchain do capture output lines with a "U" [1]
and apply a regular expression to keep only the path of the file, then 
save this output into a file.
The output file should contain a series of file relative paths in order 
to be used as input for the includesfile attribute of a patternset.

Something like that (untested) :

<exec executable="cvs" failonerror="true" dir="somerootdir">
<arg value="update"/>
<redirector output="includelist.txt">
<outputfilterchain>
<tokenfilter>
<containsregex pattern="^ U " replace=""/>
</tokenfilter>
</outputfilterchain>
</redirector>
</exec>
<fileset dir="somerootdir">
<patternset includesfile="includelist.txt"/>
</fileset>


Otherwise you can write your own ant task and make this task create 
either a patternset, a fileset, or a resource collection.

Regards,

Antoine
