%description
lbzip2 is a multi-threaded implementation of bzip2, suited for serial and
parallel processing.  On a multi-core computer, lbzip2 is commonly the fastest
bzip2 decompressor for most bz2 files found on the internet.  (On dual-core
computers, the 7za utility from the p7zip package may prove more efficient.)

lbzip2 integrates nicely with GNU tar. Even on single-core computers, lbzip2
can speed up archiving in combination with tar, because lbzip2 allows
compression to overlap with disk usage to a greater extent than bzip2 does.
