topdir is the base of several directories, including $RPM_SOURCE_DIR,
and $RPM_BUILD_DIR.  It defaults to /usr/src/redhat, but it is common
to redefine it in ~/.rpmmacros.

builddir ($RPM_BUILD_DIR) is where the source code is unpacked
(/usr/src/redhat/BUILD by default), and buildroot ($RPM_BUILD_ROOT) is
where the source is installed (typically
/var/tmp/%{name}-%{version}-%{release} or something like that).  You
unpack, ./configure, and make in builddir and then make install to
buildroot.  RPM collects the files in %files from buildroot.

Now i have a question about topdir, sourcedir, and builddir - is there
a way to get RPM to read all its config files and tell you what their
current values are?  I would like to use them in a script without
having to hard-code their values for my environment.
