The XADMaster framework for uncompressing archive files in various formats.

• The original source files can found at the developer's website (http://unarchiver.c3.cx/unarchiver).

• XAMaster is released under the GNU LGPL.

• The UniversalDetector framework is included as a dependency for XADMaster.

• The framework is mirrored here in preparation for supporting other projects on GitHub (https://github.com/arauchfuss/Simple-Comic).

• XADMaster first appeared in v2.0 of The Unarchiver.

• This mirror archives every released version of the XADMaster and UniversalDetector frameworks from 2.0 on to enable diff of the versions.

• The intent is to keep this master branch of this mirror up to date with The Unarchiver site.

Here is the original ReadMe from the The Unarchiver:

The Unarchiver is an Objective-C application for uncompressing archive files.

• Supports more formats than I can remember. Zip, Tar, Gzip, Bzip2, 7-Zip, Rar, LhA, StuffIt, several old Amiga file and disk archives, CAB, LZX, stuff I don't even know what it is. Read the wiki page for a more thorough listing of formats.
• Copies the Finder file-copying/moving/deleting interface for its interface.
• Uses character set autodetection code from Mozilla to auto-detect the encoding of the filenames in the archives.
• Supports split archives for certain formats, like RAR.
• Version 2.0 uses an archive-handling library built largely from scratch in Objective-C, which makes adding support for new formats and algorithms very easy.
• Uses libxad for older and more obscure formats. This is an old Amiga library for handling unpacking of archives.
• The unarchiving engine itself is multi-platform, and command-line tools exist for Linux, Windows and other OSes.
