What is a RPM spec file?

To create your own RPM, you need to create your own spec file (and put it in the SPECS directory) and gather into a tarball the executables, scripts, user documentation files, and configuration files you want included in the RPM. You can create your spec file by simply copying an existing spec file and modifying it.

How do I run an RPM spec file?

Install rpmrebuild and "extract" (actually re-create) the spec file of your rpm file or your already installed package. Looking at rpmrebuild's code and then actually testing it, it doesn't "extract" the spec file; it regenerates most of a spec file (header, log, pre/post scripts).

What are .spec files?
