Bruce,
I just included one file org.apache.turbine.util.SequencedHashtable. It
didn't have any dependencies. I didn't use a SequencedHashMap because it
uses Iterator and not an Enumeration. I wanted to minimize the code impact.
I also didn't know if it had to be thread safe or not.
For complex dependencies I will normally use genjar to figure that out.
Steve
