Using the lzma code from lzma-sdk 4.58, I've added support for .tar.lzma
files to setup. The lzma-sdk code is available under the following terms:
1. GNU Lesser General Public License (GNU LGPL)
2. Common Public License (CPL)
3. Simplified license for unmodified code (read SPECIAL EXCEPTION)
4. Proprietary license
I had to modify the code to add c++ guards, so #3 is out (as is #4,
natch). But, I think LGPL is ok for setup code, right? (And, of course,
my new code is provided under the GPL like most of the rest of the setup
code).
