rPath Linux Configuration for rMake

In order to build packages for different versions and architectures of rPath Linux (or any other Conary-based operating system or appliance) on a single development system, you need to tell rMake important information about each operating system and architecture that you want to build for. When you call rmake build to build a package, you can tell it an operating system context, plus architecture flavor information to build for. To tell it this, you need to add information to your ~/.rmakerc file.

This is a sample portion of a ~/.rmakerc file:
