...if you feel like zlib is not enough...

In the end, I have decided to provide 'minimal' support, without proper filter-like interface of Zlib, only providing Stream->Stream operations, with individual functions modelled after zlib.

int64  LZMACompress(Stream& out, Stream& in, int64 size, Gate2<int64, int64> progress = false, int lvl = 6);
int64  LZMACompress(Stream& out, Stream& in, Gate2<int64, int64> progress = false, int lvl = 6);
String LZMACompress(const void *data, int64 len, Gate2<int64, int64> progress = false, int lvl = 6);
String LZMACompress(const String& s, Gate2<int64, int64> progress = false, int lvl = 6);

int64  LZMADecompress(Stream& out, Stream& in, Gate2<int64, int64> progress = false);
String LZMADecompress(const void *data, int64 len, Gate2<int64, int64> progress = false);
String LZMADecompress(const String& s, Gate2<int64, int64> progress = false);

bool   LZMACompressFile(const char *dstfile, const char *srcfile, Gate2<int64, int64> progress = false, int lvl = 6);
bool   LZMACompressFile(const char *srcfile, Gate2<int64, int64> progress, int lvl = 6);
bool   LZMADecompressFile(const char *dstfile, const char *srcfile, Gate2<int64, int64> progress = false);
bool   LZMADecompressFile(const char *srcfile, Gate2<int64, int64> progress);

Filter-like class is IMO not possible using *documented* features of original code. Perhaps we can add that later...
