**************************************************************************

* Descriptive Names

* We use HPSS_HOST_TMP instead of HPSS_HOST because HPSS_HOST is

* being set in hpss_env using 'hostname', and so it always gets the

* long name. The default "%H" definition of HPSS_HOST inside

* hpss_env_defs.h gets overridden. But the long hostname is often

* too long for the very short descriptive name field. Force it

* to short name here. Unless, of course, user overrides our new

* HPSS_HOST_TMP in hpss_env...

* So to help a little more, we also provide short forms of the

* three descriptive names (logc, mvr, startup daemon) which

incorporate

* the hostname.
