про 7zip.
раньше можно было как-то так - http://www.linuxcenter.ru/lib/articles/soft/clamav_7zip.phtml или http://www.ruscentos.com/articles/bezopasnost_linux/clamav_i.../
теперь вот так - в исходниках:
$ cat ~/build/clamav-0.95.1+dfsg/libclamav/lzma/lzma.txt
LZMA SDK 4.40
-------------LZMA SDK Copyright (C) 1999-2006 Igor Pavlov
LZMA SDK provides the documentation, samples, header files, libraries,
and tools you need to develop applications that use LZMA compression.
LZMA is default and general compression method of 7z format
in 7-Zip compression program (www.7-zip.org). LZMA provides high
compression ratio and very fast decompression.
LZMA is an improved version of famous LZ77 compression algorithm.
It was improved in way of maximum increasing of compression ratio,
keeping high decompression speed and low memory requirements for
decompressing.

C/C++ source code of LZMA SDK is part of 7-Zip project.
You can find ANSI-C LZMA decompressing code at folder
C/7zip/Compress/LZMA_C
7-Zip doesn't use that ANSI-C LZMA code and that code was developed
specially for this SDK. And files from LZMA_C do not need files from
other directories of SDK for compiling.
7-Zip source code can be downloaded from 7-Zip's SourceForge page:
