# This is to fix Bug 469
# To convert from a pkg to a source pkg, we have a problem in that all we have
# is "sourcerpm", which can be a different nevra ... but just to make it fun
# the epoch isn't in the name. So we use rpmUtils.miscutils.splitFilename
# and ignore the arch/epoch ... and hope we get the right thing.
# Eg. run:
# for pkg in yb.pkgSack.returnPackages():
# if pkg.version not in pkg.sourcerpm:
