+The default RPM build directory (_topdir) has five directories in
+the top-level:
+1. BUILD/ Where the software is unpacked and built.
+2. RPMS/ Where the newly created binary package files are written.
+3. SOURCES/ Contains the original sources, patches, and icon files.
+4. SPECS/ Contains the spec files for each package to be built.
+5. SRPMS/ Where the newly created source package files are written.

+Before you begin, note the RPM sources directory on your version of
+Fedora.  The command "rpmbuild --showrc" will show the configuration
+for each of those directories. Alternatively, the command "rpm --eval
+ '%{_topdir}'" shows the current configuration for the top level
+directory and the command "rpm --eval '%{_sourcedir}'" does the same
+for the sources directory. On RHEL 5, the default RPM _topdir is
