NAME
       shtk_config_has -- Checks if a configuration variable is	set

LIBRARY
       shtk_import config

SYNOPSIS
       shtk_config_has var_name

DESCRIPTION
       The  shtk_config_has  function  checks  if  the	configuration variable
       var_name	has been previously set	by a call to shtk_config_set(3)	within
       the script or by	the user in the	configuration file.

       Note that shtk_config_has properly distinguishes	 the  case  between  a
       variable	 that  has never been defined and a variable that has been de-
       fined to	the empty value.
