NAME
    FML::Process::State - interface to handle states within current process.

SYNOPSIS
DESCRIPTION
METHODS
CURRENT MAILING LIST
BASIC RESTRICTION STATES
    CAUTION: restriction_state_*() is reset each command.

ARTICLE STATES
COMMAND PROCESSOER STATES
    command_context_init() called for each command, so restriction_state_*()
    is reset each time.

    But in the case of emulatation of listserv/majordomo emulation, we
    should pay attention for handlings of $command_mail_restrictions and
    $admin_command_mail_restrictions. The restrictions must differ among
    mailing lists. So, we do not cache the return value and always check it
    each command mail line.

FILTER STATE
  filter_state_set_error($category, $code)
    save the filter error for later use.

  filter_state_get_error($category)
    get the filter error.

SMTP STATE
  smtp_server_state_set_error($mta)
    set $mta as error for later hint.

  smtp_server_state_get_error()
    check if $mta as error for later hint.

UTILITY
  error_message_set_count($class)
    increment error count on this class $class to avoid duplicated error
    messages.

  error_message_get_count($class)
    get error count on this class $class to avoid duplicated error messages.
