Files in these directories have been compressed with the internet-standard
`gzip' program, which is free of known software patents and also
compresses better than `compress'.  Files compressed with this method 
end with `.gz'.

Gzip can also uncompress files compressed with `compress' (i.e. files
ending in `.Z'), since the uncompression algorithm is not patented.

To extract sources that are in files ending in `.tar.gz' you can use the
command

      gzip -d < foo.tar.gz | tar xf -

where `foo.tar.gz' is the name of the file.

Gzip is available in source form on this ftp archive in /pub/src/gnu/, in
the file gzip-N.N.shar, gzip-N.N.tar, and gzip-N.N.tar.gz (the last for
people who already have gzip but want to get a newer version, since the
gzipped file will transfer faster).  To find a VMS executable, read
gzip-vms.README there on a GNU archive site.  For those of you so
misfortunate as not to have an operating system, gzip is also available as
a MS-DOS executable in the file gzip-N.N.msdos.exe.
