[newbie] Packages

[Robert F. Trettel]

Hi,All

I have a question on packages that are on Linux. Is there a web site that 
gives details of what the package is and etc?? I would like to be able to 
know what to install and what I don't need. I think I am wasting space by 
taking everything that is offered in the install.
This way I will know what is what as to everyday use of Linux.

Thanks
