XFor those who *must* cram their data into the smallest possible archives, 
Xpaq is an archiver with the best lossless compression ratios now available
Xacross a wide variety of test data, according to several benchmarks.  
XIt uses adaptive weighting of context models to obtain archives that are
Xtypically about 65%-85% of the size of the corresponding best-performance 
Xgzip archives. This comes at the expense of increased memory usage
X(30MB - 1650MB, depending upon the user-specified level of compression),
Xand lower speeds(compression and decompression are often tens of times 
Xslower than bzip2 or gzip, and can be as much as several hundreds of times
Xslower). 
X
XThe command-line interface permits compression, decompression, and viewing
Xof the contents of archives.  Compression preserves directory structure
Xbut not file attributes.  There are no commands to update an existing 
Xarchive or to extract part of an archive.  Files and archives larger than
X2GB are not supported (but might work on 64-bit machines, not tested).
XFile names with nonprintable characters are not supported (spaces
Xare OK).
