In several CentOS tutorials, they advise enabling the RPMRepository. I have some questions about this repository.
It seems like it's a RedHat repository that CentOS uses as well, since it's based on RedHat. Is this correct.
How do I read the content of this rpm i.e. what packages are inside this repository. I've downloaded one of the rpm files at
http://pkgs.repoforge.org/rpmforge-release/and tried opening it in a text editor on windows, but it's not a text file. How do I know what list of packages I can get from this repository?
Is this an essential repository? What I mean is: are the packages available from this repository unavailable in any other repository? They're only available from this repo?
Are there other repositories that are of use for a system running CentOS?
