That is not to say this program is inherently unreliable.
Indeed, I very much hope the opposite is true. bzip2 has been
carefully constructed and extensively tested.

+ PATENTS:
+ To the best of my knowledge, bzip2 does not use any patented
+ algorithms. However, I do not have the resources available to
+ carry out a full patent search. Therefore I cannot give any
+ guarantee of the above statement.
