`sbt package` results in huge war file - how to make it smaller?

I'm currently using SBT to manage my Lift project. I'd like to deploy it, but when I run 'sbt package' it produces a 60MB war file. This seems pretty large - are there ways I 开发者_Python百科could cut down the size?

Thanks!

Perhaps ProGuard could help.

Turns out it was because 'sbt package' was following symlinks and packed all my images into the warfile. Thanks for the tip anyway!
