1# This file provides all the buildable and cacheable packages and
2# package outputs in your package set. These are what gets built by CI,
3# so if you correctly mark packages as
4#
5# - broken (using `meta.broken`),
6# - unfree (using `meta.license.free`), and
7# - locally built (using `preferLocalBuild`)
8#
9# then your CI will be able to build and cache only those packages for
10# which this is possible.
