[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
