    """show or change the current narrowspec

    With no argument, shows the current narrowspec entries, one per line. Each
    line will be prefixed with 'I' or 'X' for included or excluded patterns,
    respectively.

    The narrowspec is comprised of expressions to match remote files and/or
    directories that should be pulled into your client.
    The narrowspec has *include* and *exclude* expressions, with excludes always
    trumping includes: that is, if a file matches an exclude expression, it will
    be excluded even if it also matches an include expression.
    Excluding files that were never included has no effect.

    Each included or excluded entry is in the format described by
    'hg help patterns'.

    The options allow you to add or remove included and excluded expressions.

    If --clear is specified, then all previous includes and excludes are DROPPED
    and replaced by the new ones specified to --addinclude and --addexclude.
    If --clear is specified without any further options, the narrowspec will be
    empty and will not match any files.

    If --auto-remove-includes is specified, then those includes that don't match
    any files modified by currently visible local commits (those not shared by
    the remote) will be added to the set of explicitly specified includes to
    remove.

    --import-rules accepts a path to a file containing rules, allowing you to
    add --addinclude, --addexclude rules in bulk. Like the other include and
    exclude switches, the changes are applied immediately.
