I have just signed the LiCe 5.1.2 distribution. You can download the public key used for this.
All LiCe releases from now on will be signed. This is to ensure that there's no nasty people distributing any modified LiCe scripts. LiCe downloaded from this site and signed with this key will never have any backdoors or other nasty things.
Work on LiCe 5.2.0 continues, we're pretty close now!
