  class ModflowMvr(mfpackage.MFPackage):
      """
      ModflowMvr defines a mvr package.
  
      Parameters
      ----------
      simulation : MFSimulation
          Simulation that this package is a part of. Package is automatically
          added to simulation when it is initialized.
      loading_package : bool
          Do not set this parameter. It is intended for debugging and internal
          processing purposes only.
      print_input : boolean
          * print_input (boolean) keyword to indicate that the list of MVR
            information will be written to the listing file immediately after it
            is read.
      print_flows : boolean
          * print_flows (boolean) keyword to indicate that the list of MVR flow
            rates will be printed to the listing file for every stress period
            time step in which "BUDGET PRINT" is specified in Output Control. If
            there is no Output Control option and "PRINT_FLOWS" is specified,
            then flow rates are printed for the last time step of each stress
            period.
      modelnames : boolean
          * modelnames (boolean) keyword to indicate that all package names will
            be preceded by the model name for the package. Model names are
            required when the Mover Package is used with a GWF-GWF Exchange. The
            MODELNAME keyword should not be used for a Mover Package that is for
            a single GWF Model.
      budget_filerecord : [budgetfile]
          * budgetfile (string) name of the output file to write budget
            information.
      maxmvr : integer
          * maxmvr (integer) integer value specifying the maximum number of water
            mover entries that will specified for any stress period.
      maxpackages : integer
          * maxpackages (integer) integer value specifying the number of unique
            packages that are included in this water mover input file.
      packages : [mname, pname]
          * mname (string) name of model containing the package. Model names are
            assigned by the user in the simulation name file.
          * pname (string) is the name of a package that may be included in a
            subsequent stress period block. The package name is assigned in the
            name file for the GWF Model. Package names are optionally provided in
            the name file. If they are not provided by the user, then packages
            are assigned a default value, which is the package acronym followed
            by a hyphen and the package number. For example, the first Drain
            Package is named DRN-1. The second Drain Package is named DRN-2, and
            so forth.
      perioddata : [mname1, pname1, id1, mname2, pname2, id2, mvrtype, value]
          * mname1 (string) name of model containing the package, PNAME1.
          * pname1 (string) is the package name for the provider. The package
            PNAME1 must be designated to provide water through the MVR Package by
            specifying the keyword "MOVER" in its OPTIONS block.
          * id1 (integer) is the identifier for the provider. For the standard
            boundary packages, the provider identifier is the number of the
            boundary as it is listed in the package input file. (Note that the
            order of these boundaries may change by stress period, which must be
            accounted for in the Mover Package.) So the first well has an
            identifier of one. The second is two, and so forth. For the advanced
            packages, the identifier is the reach number (SFR Package), well
            number (MAW Package), or UZF cell number. For the Lake Package, ID1
            is the lake outlet number. Thus, outflows from a single lake can be
            routed to different streams, for example. This argument is an index
            variable, which means that it should be treated as zero-based when
            working with FloPy and Python. Flopy will automatically subtract one
            when loading index variables and add one when writing index
            variables.
          * mname2 (string) name of model containing the package, PNAME2.
          * pname2 (string) is the package name for the receiver. The package
            PNAME2 must be designated to receive water from the MVR Package by
            specifying the keyword "MOVER" in its OPTIONS block.
          * id2 (integer) is the identifier for the receiver. The receiver
            identifier is the reach number (SFR Package), Lake number (LAK
            Package), well number (MAW Package), or UZF cell number. This
            argument is an index variable, which means that it should be treated
            as zero-based when working with FloPy and Python. Flopy will
            automatically subtract one when loading index variables and add one
            when writing index variables.
          * mvrtype (string) is the character string signifying the method for
            determining how much water will be moved. Supported values are
            "FACTOR" "EXCESS" "THRESHOLD" and "UPTO". These four options
            determine how the receiver flow rate, :math:`Q_R`, is calculated.
            These options are based the options available in the SFR2 Package for
            diverting stream flow.
          * value (double) is the value to be used in the equation for
            calculating the amount of water to move. For the "FACTOR" option,
            VALUE is the :math:`\\alpha` factor. For the remaining options, VALUE
            is the specified flow rate, :math:`Q_S`.
      filename : String
          File name for this package.
      pname : String
          Package name for this package.
      parent_file : MFPackage
          Parent package file that references this package. Only needed for
          utility packages (mfutl*). For example, mfutllaktab package must have 
          a mfgwflak package parent_file.
