I would be happy to share code but would like to get it working 100% before
you start working on it for Linux or we will get out synch. I ended up
putting my code in ApplicationInstance.java and CacheUtil.java and left the
XDesktop stuff alone. I would like to send you code snippets and ask you
questions so you can help me work with the LRU and get cache files marked
for deletion correctly. I would like to be able to create a new CacheEntry
so I can call CacheEntry.markfordelete and then call cleanCache, but I
haven't figured it out yet because of the Version parameter. I need help.
Can I email you directly or post questions here which seems a bit
cumbersome?

Ya I have no idea how to proceed to get the jar file built so it works.
Cygwin is a mstery to me and the instructions in the link on the ITW page I
had read and are all about Linux. Hopefully someone can help me get it going
with Eclispse/Windows or maybe you can build me a jar when we get far
enough.
