RE: Centos 5.3 - Installing Package groups

[justinj]

I feel like an imbecile posting this because I'm sure it is a simple answer.

When you install Centos 5.3 you can select the package groups that you want to install. For example, in the Centos 5.3 ispconfig 3 tutorial you select Server and then install the following package groups: Editors, Text-based Internet, Development Libraries, Development Tools, DNS Name Server, FTP Server, Mail Server, MySQL Database, Server Configuration Tools, Web Server, Administration Tools, Base, and System Tools

What is the best way to install those packages and their dependencies without re-installing Centos? Is there a document or reference that shows what is included in each of those packages?

Thanks,

Justin
