#
# About
# =====
#
# This file defines jobs for our CI system and the attribute "build" is used
# as the input for packaging.
#
#
# CI details
# ==========
#
# This file defines an attribute set of derivations. Each of these attributes is
# then used in our CI system as one job to run. This way we keep the
# configuration for the CI jobs as well under version control.
#
# Run CI jobs locally
# -------------------
#
# Since it is all based on normal Nix derivations, the jobs can be tested
# locally with a run of "nix-build" like the following example:
#
#    nix-build release.nix -A test-api -I vcsserver=~/rhodecode-vcsserver
#
# Note: Replace "~/rhodecode-vcsserver" with a path where a clone of the
# vcsserver resides.
