The following options describe the type of operation to be performed:

--add-record         Create a new record with the specified limits.  Any
                       limits left unspecified with have their default 
                       values.  This option requires the --name and 
                       --quota-type options.

--create-table       Create the table if not present.  Used to initialize
                       a table.  The default limit table path is
                       "$default_limit_table".  The default tally table path is
                       "$default_tally_table".

--delete-record      Deletes a quota record from the table.  This option
                       requires the --name and --quote-type options.

--show-records       Prints out all of the quota records in the table in
                       a legible format.

--update-record      Updates a quota record with the specified limits.  Any
                       limits left unspecified will be updated with their
                       default value.  This option requires the --name and
                       --quota-type options.

The following option describes the type of table on which to operate:

--type               Specifies a table type to use.  The allowable options
                       are: "limit" or "tally".  This is required.

The following options are used to specify specific quota limits:

--Bu                 Specifies the limit of the number of bytes that may be
  --bytes-upload       uploaded.  Defaults to -1 (unlimited).  Note that any
                       value less than or equal to zero is treated as
                       "unlimited".

--Bd                 Specifies the limit of the number of bytes that may be
  --bytes-download     downloaded.  Defaults to -1 (unlimited).  Note that any
                       value less than or equal to zero is treated as
                       "unlimited".

--Bx                 Specifies the limit of the number of bytes that may be
  --bytes-xfer         transferred.  Note that this total includes uploads,
                       downloads, AND directory listings.  Defaults to
                       -1 (unlimited).  Note that any value value less than or
                       equal to zero is treated as "unlimited".

--Fu                 Specifies the limit of the number of files that may be
  --files-upload       uploaded.  Defaults to -1 (unlimited).  Note that any
                       value less than or equal to zero is treated as
                       "unlimited".

--Fd                 Specifies the limit of the number of files that may be
  --files-download     downloaded.  Defaults to -1 (unlimited).  Note that any
                       value less than or equal to zero is treated as
                       "unlimited".

--Fx                 Specifies the limit of the number of files that may be
  --files-xfer         transferred, including uploads and downloads.  Defaults
                       to -1 (unlimited).  Note that any value less than or
                       equal to zero is treated as "unlimited".

-L                   Specifies the type of limit, "hard" or "soft", of
  --limit-type         the bytes limits.  If "hard", any uploaded files that
                       push the bytes used counter past the limit will be
                       automatically deleted; if "soft", those extra bytes
                       will be allowed, but future uploads will be denied.
                       This option only makes sense if --type is "limit".

-N                   Specifies a name for the quota record.  This name
  --name               will be the user/login name, group name, or class
                       name, depending on the quota type.  This option
                       is ignored if the quota type specified is "all".

-P
  --per-session        Specifies that the quota limit is to be applied only
                       to each session, rather than persisting across
                       sessions.  By default, quotas are persistent.

-Q                   Specifies a "quota type" for this record, where
  --quota-type         the type means to which category of FTP users this
                       quota will apply.  The quota type must be one of:
                       "user", "group", "class", or "all".

The following options are miscellaneous:
