Trimming the Registry Log

What is the purpose of the Registry.log and would it be ok to trim it for space reasons? Thanks for your help –

The registry log logs the Tamino updates on the Software AG path of the registry. Together with a registry backup it ensures that you can restore a corrupted registry by restoring the backup and replaying the registry updates. Therefore after creating a new registry backup the log file can be deleted and a new one is automatically created.
