    ''''Display human readable specs with customizable formatting.
    Prints the supplied specs to the screen, formatted according to the
    arguments provided.
    Specs are grouped by architecture and compiler, and columnized if
    possible.  There are three possible "modes":
    * ``short`` (default): short specs with name and version, columnized
    * ``paths``: Two columns: one for specs, one for paths
    * ``deps``: Dependency-tree style, like ``spack spec``.

    Options can add more information to the default display. Options can
    be provided either as keyword arguments or as an argparse namespace.
    Keyword arguments take precedence over settings in the argparse
    namespace.
    Args:
    specs (list of spack.spec.Spec): the specs to display
    args (optional argparse.Namespace): namespace containing
    formatting arguments
    Keyword Args:
    mode (str): Either \'short\', \'paths\', or \'deps\'
    long (bool): Display short hashes with specs
    very_long (bool): Display full hashes with specs (supersedes ``long``)
    namespace (bool): Print namespaces along with names
    show_flags (bool): Show compiler flags with specs
    variants (bool): Show variants with specs'
