Initializes a source tree from an rpm spec file or a quilt series file.
-d Optional path prefix for the resulting source tree.
--sourcedir
Directory that contains the package sources. Defaults to \`.'.
-v Verbose debug output.
--fuzz=N
Set the maximum fuzz factor (needs rpm 4.6 or later).
--slow Use the original, slow method to process the spec file. This is the
default for now, but that might change in the future. In this mode,
rpmbuild generates a working tree in a temporary directory while all
its actions are recorded, and then everything is replayed from scratch
in the target directory.
--fast Use an alternative, faster method to process the spec file. In this
mode, rpmbuild is told to generate a working tree directly in the
target directory.
