Here are two new ant tasks - BZip2 and BUnzip2. �These
two tasks use the BZip2 compression algorithm (Visit:
http://sourceware.cygnus.com/bzip2/�for more info.) for
packing and unpacking.
These tasks resemble GZip and GUnzip tasks in input,
input validation, etc. �Hence, I refactored GZip and
GUnzip tasks as well so that the tasks GZip and BZip2
extend from a common base class named Pack, and
GUnzip and BUnzip2 extend from a common base class named
Unpack. �This lays the foundation for creating more Pack
tasks based on different algorithms like lzop, etc. in
the future.
The BZip2 and BUnzip2 tasks depend upon 4 classes:
BZip2Constants.java
CBZip2InputStream.java
CBZip2OutputStream.java
CRC.java
Keiron Liddle (keiron@aftexsw.com) has graciously
accepted to contribute the above code files he has
authored, under ASF license - many thanks to him. �I
have packaged them under org.apache.tools.bzip2,
mimicking the package naming style that has been used
for zip and tar tools we already have. �I have also
given proper credits to him in the code. �Perhaps, this
needs to exist under jakarta-commons, as Stefan had
suggested, but till then...
