5 # The candidate repository contains unsupported prerelease packages. Use at
6 # your own risk.
7 #
8 # Note, however, that the candidate repository is usually empty; it is
9 # used when we're preparing (and testing) a new release. Therefore, it
10 # should be relatively safe.
11 #
12 # There is also another "continuous" repository, for which packages get
13 # recompiled for each and every change to the source. This isn't listed
14 # (so that it can't be accidentally enabled), but the configuration is
