RPM - source vs binary

reference : http://www.rpm.org/max-rpm/ch-rpm-build.html

2 kind of packages : binary and source (checked by cmd : file xxxx.rpm)

If it is a source, after you install using "rpm -ivv xxxx.rpm" will generate:
1. patch(es) file
2. SPEC file --> is similar with a Make file
3. xxx.tgz --> in which some files of .c and .h located

From this point the steps would be:
-> BUILD -> BIN RPM package and SourceRPM package
Note: the first source is the original, this one is the one after build. See below.

The normal directory layout consists of a single top-level directory (The default name is /usr/src/redhat), with five subdirectories. The five subdirectories and their functions are:

*/usr/src/redhat/SOURCES — Contains the original sources, patches, and icon files.
*/usr/src/redhat/SPECS — Contains the spec files used to control the build process.
*/usr/src/redhat/BUILD — The directory in which the sources are unpacked, and the software is built.
*/usr/src/redhat/RPMS — Contains the binary package files created by the build process.
*/usr/src/redhat/SRPMS — Contains the source package files created by the build process.
