# The original sources are not included in the source RPM.
# If we included them, then the source RPMs for each target
# would duplicate MBs of source unnecessarily.  This is 
# a duplication of over 30 MBs of source for each of
# the more than 10 targets it is possible to build.
#
# You can get them yourself from the Internet and copy them to
# your /usr/src/redhat/SOURCES directory ($RPM_SOURCE_DIR).
# Or you can try the ftp options of rpm :-)
