When source RPMs are installed, the sources will be in
    $HOME/RPM/SOURCES
and the spec files will be in
    $HOME/RPM/SPECS

When using either -bp, -bc, -bi, -bb, or -ba to build RPMs,
the building occurs in
    $HOME/RPM/BUILD
and the "chrooted installation" occurs in
    $HOME/RPM/tmp

Built RPMs will be in either
    $HOME/RPM/BUILD/i586
or
    $HOME/RPM/BUILD/noarch
