  def caveats
    <<~EOS
      In order to speed up JIT, run 'spicy-precompile-headers' after
      installation. This script places precompiled headers used during
      JIT in '$HOME/.cache/spicy'.

      Per-module JIT results can be cached with ccache which should speed up
      subsequent compilations. For that, set
      'HILTI_CXX_COMPILER_LAUNCHER=ccache' in your environment and make sure
      ccache is installed.
