1 # To enable the candidate repository, uncomment the below line, put "deb" in
2 # front of it, and run "dpkg-reconfigure eid-archive" to enable the archive
3 # key.
4 #
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
15 # the same as the below, with "candidate" replaced by "continuous".

18 # NOTE: files2.eid.belgium.be is a mirror for the main repository ONLY.
19 # That is, it does not contain the continuous or candidate repositories.

21 # The regular repository with released packages. This is what you should
