# Jpackage #
############
# JPackage is a GREAT repository for Java Software.
# However, you may have to compile some SRPMs to use it,
# so it's commented out by default. See
# <http://mirrors.sunsite.dk/jpackage/1.6/generic/non-free/SRPMS>
# For the SRPMs, and <http://www.jpackage.org/rebuilding.php> for
# the general details.
#
# Note: JPackage IS compatible with the fedora.us repositories.
# You can use JPackage and fedora.us at the same time, without
# any trouble. It's also compatible with the Alternate Repositories,
# for the most part.
