   7 /*      Postfix master - global configuration file access
   8 /* SYNOPSIS

  11 /*      void    master_vars_init()
  12 /* DESCRIPTION
  13 /*      master_vars_init() reads values from the global Postfix configuration
  14 /*      file and assigns them to tunable program parameters. Where no value
  15 /*      is specified, a compiled-in default value is used.
