How to let unison output the results of comparing replicas but not synchronize them

Question

I have a question about the file synchronizer, unison. Is there a way to let unison compare two replicas and output the difference (to the standard output or a file) but not execute any updates?

I could do this by just hitting / (skip) for each update possibility in the interactive session, but I have more than a thousand lines of possibilities and lost patience to hold the / key for a long time. Is there a way to skip all automatically?

I don't know if this is a practical solution for you, but if you run Unison in text mode (unison -ui text), you can get an overview of all content to be transmitted by typing an upper-case L at the prompt (when it's ready to reconcile the changes). Perhaps you could automate this using expect?
