lzop is a file compressor which is very similar to gzip.

lzop uses the LZO data compression library for compression services, and its main advantages over gzip are much higher compression and decompression speed (at the cost of some compression ratio).


1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.

Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for.

2. Type `make' to compile the package.

3. Optionally, type `make check' to run any self-tests that come with the package.

4. Type `make install' to install the programs and any data files and documentation.

5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'.

There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution.

Here are some key features of "Lzop":
speed (both compression and decompression)
reasonable drop-in compatibility to gzip

What's New in This Release:
Made lzop compile with LZO v2.
Under Windows files are now opened using the _O_SEQUENTIAL flag, which results in a major speedup when (de)compressing large files.
Under MacOS X, the configure script now will use the `-no-cpp-precomp' compiler option in order to work around bugs in Apple's native "smart" preprocessor.
File sizes > 2GB are correctly displayed.
