[CentOS] Licences

Hi,

	I'm looking for a way to determine the licenses of packages we're using.

	Is there a command (rpm, yum, up2date...) that will take the package 
name as argument and return me the licence?

	Or is everything included with Centos 4 GPL?  That is the only licence 
I found in the repositories...  I remember that RH had the habit of 
putting all the applicable licences on the distros' CD.

Thanks,
