This is a client for xadmaster.library to enable UnArc to extract 7-Zip
archives.

It supports PPMd (OS4 build only), BZip2, LZMA, LZMA2 and Copy (no
compression) methods with BCJ and BCJ2 filters.  Other methods may be
supported in future, please send me any unsupported archives.

Note that hook functions (eg. clicking "stop" in UnArc) don't work currently,
and the compressed size is not decoded.

If you want a default icon, copy def_7zip.info to envarc:sys, and add the
following to DefIcons:

Filetype: 7zip
Match: 7z\xBC\xAF'\x1C

Please report any bugs to chrisunsatisfactorysoftware.co.uk

A big thank you to Dag Ågren for his rewritten PPMd decoder, without which
the PPMd compression method would not be possible.

Thanks to Stephan Rupprecht for some pointers on creating OS4 native XAD
clients, and to Philippe Bovier for testing the 68k version.  The def_7zip icon
is by Martin Merz (www.masonicons.de), the others are 256 colour icons by Ken
"Ken's Icons" Lester.

HISTORY

2.1 (07.09.2009) SEVENTH RELEASE
Updated to LZMA SDK 9.07BETA
- Now supports LZMA2 compression
OS4 version compiled with latest SDK.
Thought it was appropriate to bump version to 2 as LZMA SDK has had a massive
5 version bump :)

1.9 (05.02.2009) SIXTH RELEASE PPMd compression supported  - Unfortunately this
is OS4 only currently as my 68k build gets stuck in a loop    when starting the
PPMd decoder.
Recompiled with latest SDKs and compilers.

1.8 (02.11.2008) FIFTH RELEASE
Updated to LZMA SDK 4.60BETA
OS4 version can now page to disk on OS4.1+ allowing extraction of large files.

Updated to LZMA SDK 4.58BETA (speed optimisations)

1.6 (03.07.2008)
Converted to newlib and sobjs (OS4 only)

1.5 (09.03.2008) THIRD RELEASE
BZip2 method added.

1.4 SECOND RELEASE
Now extracts the the datestamp of compressed files.

1.3
An order of magnitude faster!  An archive which reportedly took 1hr40 with v1.1

1.2

of reporting an error.
First 68k version.
