Thanks, everyone, for the suggestions.  Sounds like <for> is probably
the way to go - I found a build script from another of our projects
that already uses it (looks like Netbeans' mobility pack includes the
ant-contrib jar, and luckily I did include that option when I
installed it).

Another possiblity I was wondering about, given jslint is itself
written in javascript, was using the <script> optional task to run it
rather than calling Rhino.  Ideally, I'd use the src attribute to read
in an unmodified jslint.js then some inline javascript to set up
various options and call it.  Can that be done in a single <script>
task, though? i.e. would it read/execute the external src file and
then execute the inline script as well?  Or, if I use more than one
<script> task in a target (one using src, one with the inline script)
would the objects/functions defined in the first one still be
available in the subsequent task or does each one run in a completely
separate/clean context?
