This is a *NON official* patch to GNU tar 1.11.1 to support gzip. With
this patch, tar -cz invokes gzip, tar -cZ invokes compress. You can
use tar -xz to extract both compressed and gzip'ed tar files.
Future versions of GNU tar will support gzip.
tar and gzip are available on all GNU archive sites, such as
prep.ai.mit.edu:/pub/gnu and its mirrors.
