XZ for Java

===========

Introduction

    This aims to be a complete implementation of XZ data compression

    in pure Java. Features:

      - Full support for the .xz file format specification version 1.0.4

      - Single-threaded streamed compression and decompression

      - Single-threaded decompression with limited random access support

      - Raw streams (no .xz headers) for advanced users, including LZMA2

        with preset dictionary

    Threading is planned but it is unknown when it will be implemented.

    For the latest source code, see the project home page:

        https://tukaani.org/xz/java.html

    The source code is compatible with Java 5 and later.

Building

    It is recommended to use Apache Ant. Type "ant" to compile the

    classes and create the .jar files. Type "ant doc" to build the

    javadoc HTML documentation. Note that building the documentation

    will download a small file named "package-list" from Oracle to

    enable linking to the documentation of the standard Java classes.

    If you are using OpenJDK 9 or later, you will need to edit the

    "sourcever = 1.5" line in the file "build.properties" before

    running "ant". Set it to 1.6 or higher. The default value 1.5

    isn't supported by OpenJDK 9 or later.

    If you cannot or don't want to use Ant, just compile all .java

    files under the "src" directory.

Demo programs

    You can test compression with XZEncDemo, which compresses from

    standard input to standard output:

        java -jar build/jar/XZEncDemo.jar < foo.txt > foo.txt.xz

    You can test decompression with XZDecDemo, which decompresses to

    standard output:

        java -jar build/jar/XZDecDemo.jar foo.txt.xz
