allows to compress and uncompress Files, and to read and write compressed files using standard stream
methods. It allows to compress and uncompress strings in memory, too.
Currently It can use two algorithms, provided by zlib and libbzip2. The more known programs using these algorithms are the command line tools "gzip" and "bzip2", so you can handle the files generated by these programs.
uses internally "libz" and "libbz2" libraries, so you need to install these libraries in the computers that are going to use the compression component
. If you plan to use just one of these algorithms, you don't need to install both libraries.

All common GNU/Linux
distributions include packages for these libraries, FreeBSD and other Unixes too. Both data compressors are patent-free, and currently can be used even in not open source programs, if you follow all the instructions contained in their licenses.
