# To avoid putting too much effort in this legacy code, we just build all servers in one image.
# NOTE: unlike cabal build, run, and repl, cabal install ignores specified targets, so
# `cabal install borrowit reservations webforms` will also install importer and piglet. Builds are reasonably fast
# tough, so we just use `all`.
