Can you generate the documentation for the following Python 3 function
def set_perms(obj_name,

    Set permissions for the given path

    .. versionadded:: 2019.2.0

    Args:

        obj_name (str):
            The name or full path to the object

        obj_type (Optional[str]):
            The type of object for which to check permissions. Default is 'file'

        grant_perms (dict):
            A dictionary containing the user/group and the basic permissions to
            grant, ie: ``{'user': {'perms': 'basic_permission'}}``. You can also
            set the ``applies_to`` setting here. The default for ``applise_to``
            is ``this_folder_subfolders_files``. Specify another ``applies_to``
            setting like this:

            .. code-block:: yaml

                {'user': {'perms': 'full_control', 'applies_to': 'this_folder'}}

            To set advanced permissions use a list for the ``perms`` parameter,
            ie:

            .. code-block:: yaml

                {'user': {'perms': ['read_attributes', 'read_ea'], 'applies_to': 'this_folder'}}

            To see a list of available attributes and applies to settings see
            the documentation for salt.utils.win_dacl.

            A value of ``None`` will make no changes to the ``grant`` portion of
            the DACL. Default is ``None``.

        deny_perms (dict):
            A dictionary containing the user/group and permissions to deny along
            with the ``applies_to`` setting. Use the same format used for the
            ``grant_perms`` parameter. Remember, deny permissions supersede
            grant permissions.

            A value of ``None`` will make no changes to the ``deny`` portion of
            the DACL. Default is ``None``.

        inheritance (bool):
            If ``True`` the object will inherit permissions from the parent, if
            ``False``, inheritance will be disabled. Inheritance setting will
            not apply to parent directories if they must be created. Default is
            ``False``.

        reset (bool):
            If ``True`` the existing DCL will be cleared and replaced with the
            settings defined in this function. If ``False``, new entries will be
            appended to the existing DACL. Default is ``False``.

        bool: True if successful

    public :
        Make this image public available on this instance?
            None on source_type LXD means copy source
            None on source_type file means False

    auto_update :
        Try to auto-update from the original source?
            None on source_type LXD means copy source
            source_type file does not have auto-update.

def hosted_zone_present(name, Name=None, PrivateZone=False,

                        region=None, key=None, keyid=None, profile=None):
    '''
    Ensure a hosted zone exists with the given attributes.

    name
        The name of the state definition.

    Name
        The name of the domain. This should be a fully-specified domain, and should terminate with a
        period. This is the name you have registered with your DNS registrar. It is also the name
        you will delegate from your registrar to the Amazon Route 53 delegation servers returned in
        response to this request.  If not provided, the value of name will be used.

    PrivateZone
        Set True if creating a private hosted zone.  If true, then 'VPCs' is also required.

    Comment
        Any comments you want to include about the hosted zone.

    CallerReference
        A unique string that identifies the request and that allows create_hosted_zone() calls to be
        retried without the risk of executing the operation twice.  This helps ensure idempotency
        across state calls, but can cause issues if a zone is deleted and then an attempt is made
        to recreate it with the same CallerReference.  If not provided, a unique UUID will be
        generated at each state run, which can potentially lead to duplicate zones being created if
        the state is run again while the previous zone creation is still in PENDING status (which
        can occasionally take several minutes to clear).  Maximum length of 128.

    VPCs
        A list of dicts, each dict composed of a VPCRegion, and either a VPCId or a VPCName.
        Note that this param is ONLY used if PrivateZone == True

        VPCId
            When creating a private hosted zone, either the VPC ID or VPC Name to associate with is
            required.  Exclusive with VPCName.

        VPCName
            When creating a private hosted zone, either the VPC ID or VPC Name to associate with is
            required.  Exclusive with VPCId.

        VPCRegion
            When creating a private hosted zone, the region of the associated VPC is required.  If
            not provided, an effort will be made to determine it from VPCId or VPCName, if
            possible.  This will fail if a given VPCName exists in multiple regions visible to the
            bound account, in which case you'll need to provide an explicit value for VPCRegion.

    PrivateZone
        Set to True if the resource record should be in a private zone, False if public.

    Name
        Name of the Route 53 resource record being managed.

    Type
        The record type (A, NS, MX, TXT, etc.)

    SetIdentifier
        Valid for Weighted, Latency, Geolocation, and Failover resource record sets only.
        An identifier that differentiates among multiple resource record sets that have the same
        combination of DNS name and type.  The value of SetIdentifier must be unique for each
        resource record set that has the same combination of DNS name and type. Omit SetIdentifier
        for any other types of record sets.

    Weight
        Valid for Weighted resource record sets only.  Among resource record sets that have the
        same combination of DNS name and type, a value that determines the proportion of DNS
        queries that Amazon Route 53 responds to using the current resource record set. Amazon Route
        53 calculates the sum of the weights for the resource record sets that have the same
        combination of DNS name and type. Amazon Route 53 then responds to queries based on the
        ratio of a resource's weight to the total.

        Note the following:

        - You must specify a value for the Weight element for every weighted resource record set.
        - You can only specify one ResourceRecord per weighted resource record set.
        - You can't create latency, failover, or geolocation resource record sets that have the
          same values for the Name and Type elements as weighted resource record sets.
        - You can create a maximum of 100 weighted resource record sets that have the same values
          for the Name and Type elements.
        - For weighted (but not weighted alias) resource record sets, if you set Weight to 0 for a
          resource record set, Amazon Route 53 never responds to queries with the applicable value
          for that resource record set.  However, if you set Weight to 0 for all resource record
          sets that have the same combination of DNS name and type, traffic is routed to all
          resources with equal probability.  The effect of setting Weight to 0 is different when
          you associate health checks with weighted resource record sets. For more information,
          see `Options for Configuring Amazon Route 53 Active-Active and Active-Passive Failover`__
          in the Amazon Route 53 Developer Guide.

          .. __: http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/dns-failover-configuring-options.html

    Region
        Valid for Latency-based resource record sets only.  The Amazon EC2 Region where the resource
        that is specified in this resource record set resides. The resource typically is an AWS
        resource, such as an EC2 instance or an ELB load balancer, and is referred to by an IP
        address or a DNS domain name, depending on the record type.

    GeoLocation
        Geo location resource record sets only.  A dict that lets you control how Route 53 responds
        to DNS queries based on the geographic origin of the query.  For example, if you want all
        queries from Africa to be routed to a web server with an IP address of 192.0.2.111, create a
        resource record set with a Type of A and a ContinentCode of AF.

        .. code-block:: text

            ContinentCode
                The two-letter code for the continent.
                Valid values: AF | AN | AS | EU | OC | NA | SA
                Constraint: Specifying ContinentCode with either CountryCode or SubdivisionCode
                            returns an InvalidInput error.
            CountryCode
                The two-letter code for the country.
            SubdivisionCode
                The code for the subdivision, for example, a state in the United States or a
                province in Canada.

        Notes

        - Creating geolocation and geolocation alias resource record sets in private hosted zones
          is not supported.
        - If you create separate resource record sets for overlapping geographic regions (for
          example, one resource record set for a continent and one for a country on the same
          continent), priority goes to the smallest geographic region. This allows you to route
          most queries for a continent to one resource and to route queries for a country on that
          continent to a different resource.
        - You can't create two geolocation resource record sets that specify the same geographic
          location.
        - The value ``*`` in the CountryCode element matches all geographic locations that aren't
          specified in other geolocation resource record sets that have the same values for the
          Name and Type elements.
        - Geolocation works by mapping IP addresses to locations.  However, some IP addresses
          aren't mapped to geographic locations, so even if you create geolocation resource
          record sets that cover all seven continents, Amazon Route 53 will receive some DNS
          queries from locations that it can't identify.  We recommend that you
          create a resource record set for which the value of CountryCode is
          ``*``, which handles both queries that come from locations for which you
          haven't created geolocation resource record sets and queries from IP
          addresses that aren't mapped to a location.  If you don't create a ``*``
          resource record set, Amazon Route 53 returns a "no answer" response
          for queries from those locations.
        - You can't create non-geolocation resource record sets that have the same values for the
          Name and Type elements as geolocation resource record sets.

    TTL
        The resource record cache time to live (TTL), in seconds.
        Note the following:

        - If you're creating an alias resource record set, omit TTL. Amazon Route 53 uses the
          value of TTL for the alias target.
        - If you're associating this resource record set with a health check (if you're adding
          a HealthCheckId element), we recommend that you specify a TTL of 60 seconds or less so
          clients respond quickly to changes in health status.
        - All of the resource record sets in a group of weighted, latency, geolocation, or
          failover resource record sets must have the same value for TTL.
        - If a group of weighted resource record sets includes one or more weighted alias
          resource record sets for which the alias target is an ELB load balancer, we recommend
          that you specify a TTL of 60 seconds for all of the non-alias weighted resource record
          sets that have the same name and type. Values other than 60 seconds (the TTL for load
          balancers) will change the effect of the values that you specify for Weight.

    ResourceRecords
        A list, containing one or more values for the resource record.  No single value can exceed
        4,000 characters.  For details on how to format values for different record types, see
        `Supported DNS Resource Record Types`__ in the Amazon Route 53 Developer Guide.

        .. __: http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/ResourceRecordTypes.html

        Note:  You can specify more than one value for all record types except CNAME and SOA.

        It is also possible to pass "magic" strings as resource record values.  This functionality
        can easily be extended, but for the moment supports the following:

            'magic:ec2_instance_tag:some_tag_name:some_string:some_instance_attr'

        This tells salt to lookup an EC2 instance with a tag 'some_tag_name' which has the value
        'some_string' and substitute the 'some_instance_attr' attribute of that instance as the
        resource record value being evaluated.

        This should work generally for any EC2 instance tags, as long as the instance attribute
        being fetched is available to getattr(instance, 'attribute') as seen in the code below.
        Anything else will most likely require this function to be extended to handle it.

        The canonical use-case for this (at least at our site) is to query the Name tag (which
        we always populate with the host's FQDN) to lookup the public or private IPs bound to the
        instance, so we can then automgically create Route 53 records for them.

    AliasTarget
        The rules governing how to define an AliasTarget for the various supported use-cases are

Can you generate the documentation for the following Python 3 function
def get_module_environment(env=None, function=None):
    '''
    Get module optional environment.

    To setup an environment option for a particular module,
    add either pillar or config at the minion as follows:

    system-environment:
      modules:
        pkg:
          _:
            LC_ALL: en_GB.UTF-8

        pkg:
          _:
            LC_ALL: en_US.Latin-1
            NAME: Fred

    So this will export the environment to all the modules,
    states, returnes etc. And calling this function with the globals()
    in that context will fetch the environment for further reuse.

    Underscore '_' exports environment for all functions within the module.
    If you want to specifially export environment only for one function,
    specify it as in the example above "install".

    First will be fetched configuration, where virtual name goes first,
    then the physical name of the module overrides the virtual settings.
    Then pillar settings will override the configuration in the same order.
