A precision here: rpm -bb is for rebuilding a package built by someone
else, in case you are the original author you would also want the SRPM
and in that case you use "rpm -ba"

Notice that if you list a directory everything under it will be included.
Now there are some cases where you want to include a directory but not
all of its files. You could omit the directory but in tha case it
would be unowned and would not be removed when the user uninstalls the
package. Solution is to use the %dir clause. This includes the
directory in the package but not what is under it.
Another trick is to use the "%files -f filename packagename". The
file will cotain a list of files to be included in the package thus
making possible dynaic building of the file list.

when you do an 'rpm -i mysourcerpm' than it puts the spec file in
SPECS and the source and patches in SOURCES directories.
rpm -bp Specfile
will untar the sources and apply patches
rpm -bc Specfile
will do the above and compile the software.
rpm -bi Specfile
will do the above and additiion wil build the installation tree for
the softwre. This will trash your if you don't use the BuildRoot
cluase. Then you can study what files have been installed and list
them in the %files section. By the way 'rpm -bi checks that the files
listed in %files exist so this is acleaner way to check you didn't
forget anything than removing the %clean clause.
rpm -bb Specfile
will do waht rpm -bi does but in addition will put the install tree
into a compressed cpio with a header. That is an RPM
rpm -ba Specfile
will do what rpm -bb does and in addition will put
the sources, patches and spec into an SRPM.
Don't forget the --shortcircuit clause for debugging purposes.
