# Run like this: | |
# nix-build ./tarball.nix | |
# or | |
# nix-build --argstr hydraName snabb-lwaftr --argstr version v1.0.0 ./tarball.nix | |
# and the release tarball will be written to ./result/ . It will contain | |
# both the sources and the executable, patched to run on Linux LSB systems. | |
# | |
# NOTE: Hydra doesn't use the --tags parameter in the "git describe" command (see | |
# https://github.com/NixOS/hydra/blob/master/src/lib/Hydra/Plugin/GitInput.pm#L148 | |
# ), so lightweight (non-annotated) tags are not found. Always create annotated | |
# tags with the "git tag" command by using one of the -a, -s or -u options. | |
