+# CentOS-CR.repo

+#

+# The Continuous Release ( CR )  repository contains rpms that are due in the next

+# release for a specific CentOS Version ( eg. next release in CentOS-7 ); these rpms

+# are far less tested, with no integration checking or update path testing having

+# taken place. They are still built from the upstream sources, but might not map 

+# to an exact upstream distro release.

+#

+# These packages are made available soon after they are built, for people willing 

+# to test their environments, provide feedback on content for the next release, and

+# for people looking for early-access to next release content.

+#

+# The CR repo is shipped in a disabled state by default; its important that users 

+# understand the implications of turning this on. 

+#

+# NOTE: We do not use a mirrorlist for the CR repos, to ensure content is available

+#       to everyone as soon as possible, and not need to wait for the external

+#       mirror network to seed first. However, many local mirrors will carry CR repos

+#       and if desired you can use one of these local mirrors by editing the baseurl

+#       line in the repo config below.
