Changes in version 1.7: The fast encoder, which produces a compression speed and ratio comparable to those of gzip, has been ported from lzip. The option "-0" has been ported from lzip to minilzip. If all the data to be compressed are written in advance, lzlib will automatically adjust the header of the compressed data to use the smallest possible dictionary size. This feature reduces the amount of memory needed for decompression and allows minilzip to produce identical compressed output as lzip. The targets "install-compress", "install-strip-compress", "install-info-compress" and "install-man-compress" have been added to the Makefile.
