uncompressing GNU-Zip files on a IIGS - how!?

[ldawson@nde.unl.edu (larry dawson)]

I've found a lot of text files in archives with an extension of.gz and have
not been able to uncompress then with PMPZip.  Does anyone know if there is
a program that will uncompress them on a IIGS?  In something that I read, 
I gather they can be uncompressed online, but the system I'm on doesn't do it
- only 'tar' compressed files.  Is there something our system's operator 
can add that will delete the need of doing it on my own computer?
Thanks for your help.
