WARNING:
This program (attempts to) compress data by performing several
non-trivial transformations on it. Unless you are 100% familiar
with *all* the algorithms contained herein, and with the
consequences of modifying them, you should NOT meddle with the
compression or decompression machinery. Incorrect changes can
and very likely *will* lead to disasterous loss of data.
DISCLAIMER:
I TAKE NO RESPONSIBILITY FOR ANY LOSS OF DATA ARISING FROM THE
USE OF THIS PROGRAM, HOWSOEVER CAUSED.
Every compression of a file implies an assumption that the
compressed file can be decompressed to reproduce the original.
Great efforts in design, coding and testing have been made to
ensure that this program works correctly. However, the
complexity of the algorithms, and, in particular, the presence
of various special cases in the code which occur with very low
but non-zero probability make it impossible to rule out the
possibility of bugs remaining in the program. DO NOT COMPRESS
ANY DATA WITH THIS PROGRAM UNLESS YOU ARE PREPARED TO ACCEPT THE
POSSIBILITY, HOWEVER SMALL, THAT THE DATA WILL NOT BE RECOVERABLE.
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.

All the other scripts and control files for building and installing
bzip2 under Debian GNU/Linux are also under the GNU General Public
License (GPL) version 2 or later.
