[CentOS] packaging local builds

I have built software on unix/Linuix many times, but now I want to move two packages that I have built on one machine to another (both CentOS4.2), and the time seems ripe to discover how to use rpm. The packages are subversion-1.3.0 and swig-1.3.28. How do I turn the the results of the build process into rpms?

As I am a digest subscriber, the favour of a direct copy of any reply to the list is appreciated.

Regards, Jim
