Off-the-record (otr) messaging library toolkit

otr allows you to have private conversations over im by providing:
- encryption
- no one else can read your instant messages.
- authentication
- you are assured the correspondent is who you think it is.
- 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.
- perfect forward secrecy
- if you lose control of your private keys, no previous conversation
is compromised.
this package contains the program files for the otr library.
