"""SCons.Tool.rpmutils.py

RPM specific helper routines for general usage in the test framework
and SCons core modules.

Since we check for the RPM package target name in several places,
we have to know which machine/system name RPM will use for the current
hardware setup. The following dictionaries and functions try to
mimic the exact naming rules of the RPM source code.
They were directly derived from the file "rpmrc.in" of the version
rpm-4.9.1.3. For updating to a more recent version of RPM, this Python
script can be used standalone. The usage() function below shows the
exact syntax.
