/**
 * @defgroup globus_gsi_cert_utils_activation Activation
 * @ingroup globus_gsi_cert_utils
 *
 * Globus GSI Cert Utils uses standard Globus module activation and
 * deactivation.  Before any Globus GSI Cert Utils functions are called, the
 * following function must be called:
 *
   @code
        globus_module_activate(GLOBUS_GSI_CERT_UTILS_MODULE)
   @endcode
 *
 *
 * This function returns GLOBUS_SUCCESS if Globus GSI Credential was
 * successfully initialized, and you are therefore allowed to
 * subsequently call Globus GSI Cert Utils functions.  Otherwise, an error
 * code is returned, and Globus GSI Cert Utils functions should not be
 * subsequently called. This function may be called multiple times.
 *
 * To deactivate Globus GSI Cert Utils, the following function must be called:
 *
   @code
      globus_module_deactivate(GLOBUS_GSI_CERT_UTILS_MODULE)
   @endcode
 *
 * This function should be called once for each time Globus GSI Cert Utils
 * was activated.
