[Alug] tar and gzip

Hullo list, When a directory is tarred and gzipped, will it also include any symlinked directories? e.g first directory to be gzipped is /home/jenny, which contains a link to /var/www second directory to be gzipped is /var/www Tarball is created from both these directories. Burning Q: are the files in /var/www being saved in the tarball twice? Jen.
