    with Amber tools.

    A manual download is required for Ambers. Spack will search your current
    directory for the download files. Alternatively, add the files to a mirror
    so that Spack can find them. For instructions on how to set up a mirror, see
    https://spack.readthedocs.io/en/latest/mirrors.html

    Note: Only certain versions of ambertools are compatible with amber.
    Only the latter version of ambertools for each amber version is supported.
