All packages that are included in the official Debian distribution are free according to the Debian Free Software Guidelines. This assures free use and redistribution of the packages and their complete source code. The official Debian distribution is what is contained in the main section of the Debian archive.
As a service to our users, we also provide packages in separate sections that can not be included in the main distribution due to either a restrictive license or legal issues. They include:
Contrib
Packages in this area are freely licensed by the copyright holder but depend on other software that is not free.
Non-Free
Packages in this area have some onerous license condition restricting use or redistribution of the software.
Non-US/Main
Packages in this area are free themselves but cannot be exported from a server in the U.S.
Non-US/Non-Free
Packages in this area have some onerous license condition restricting use or redistribution of the software. They cannot be exported from the U.S. because they are encryption software packages that are not handled by the export control procedure that is used for the packages in Main or they cannot be stored on a server in the U.S because they are encumbered by patent issues.
