+ (description
+ "Pidgin-OTR is a plugin that adds support for OTR to the Pidgin instant
+messaging client. OTR (Off-the-Record) Messaging allows you to have private
+conversations over instant messaging by providing: (1) Encryption: No one else
+can read your instant messages. (2) Authentication: You are assured the
+correspondent is who you think it is. (3) Deniability: The messages you send
+do not have digital signatures that are checkable by a third party. Anyone
+can forge messages after a conversation to make them look like they came from
+you. However, during a conversation, your correspondent is assured the
+messages he sees are authentic and unmodified. (4) Perfect forward secrecy:
+If you lose control of your private keys, no previous conversation is
+compromised.")
