Programmatically create a fileset and reference

Hi All,

I have created dozen of custom tasks before, but find myself struggling
with this one. I wish to create a task that does the following:

1. Accepts a file attribute to represent the absolute path of a file
contains comma separated absolute paths.
  a. this file name will be read in, parsed and each file found will
be added to a fileset object, which in term is added to a resources object.
2. Accepts a id property
  a. this id will be the id of the resource created in step 1a.

So essentially I want...

  <csvtofileset file="csv.file.name" id="some.id.name">

I am unclear on how to add the fileset i create in my code to the
project. Additionally I am unsure of how to assign this an 'id' that I
can reference elsewhere. Basically what I want to be able to do is
create a collection of files on the fly which I can reference on the
fly.  Essentially in the following snippet, the resources element would
be replaced by my new task element

<project name="test" basedir="." default="test">

 <!-- old -->
  <resources id="fsd">
     <fileset file="c:\temp\db2_test\db2jcc.jar" />  
     <fileset file="c:\temp\db2_test\db2jcc_license_cu.jar" />  
  </resources>
  <!-- old -->

  <!-- new -->
      <csvtofileset file="csv.file.name" id="fsd">
  <!-- new -->

 <target name="test">
      <copy toDir="c:\temp\ failonerror="true">
        <resources refid="fsd"/>
      </copy>
 </target>
</project>


Any help at all would be appreciated.
