The CentOS Distribution is a free enterprise class computing platform

to anyone who wishes to use it.  The CentOS Distribution is built from

publicly available open source SRPMS provided by a prominent North

American Enterprise Linux vendor.  The CentOS Distribution conforms

fully with the upstream vendors redistribution policies and aims to be

100% binary compatible (The CentOS Project mainly changes packages to

remove upstream vendor branding and artwork.).

The CentOS Project releases its CentOS Distribution as a GPL work. The

GPL applies to the software collection known as the CentOS

Distribution.  Individual packages included in the distribution

include their own licenses and the GPL applies to all packages that it

does not clash with. If there is a clash between the GPL and

individual package licenses, the individual package license applies

instead.

Neither the CentOS Project (we who build CentOS Distribution) nor any

version of CentOS Distribution is affiliated with, produced by, or

supported by the prominent North American Enterprise Linux vendor.

Neither does our software contain the upstream vendor's product ...

although it is built from the same open source SRPMS as the upstream

enterprise products.
