Those files with the ".Z" suffix are compressed using the standard unix "compress" command. They can be decompressed on Unix systems using the "uncompress" command. On other systems, the GNU tool "gzip", can be used to uncompress the files. The version of gzip for PC's is provided in the file "gzip-1.2.4.msdos.exe" in this directory. The files can be uncompressed on PC's using the commmand "gzip -ad .Z" The gzip for other platforms is provided in source in the file gzip-1.2.4.tar and can be compiled for a large number of platforms. Many are available at anonymous ftp locations in executable form.
