I'm glad to hear tht others are dubious on end-running EXPLAIN.  EXPLAIN is
supported beautifully by RMIT (Australia), in their SIM (Structured
Information Manager- http://www.simdb.com).

Allow me to add a line of rant:

It's time software bit the bullet and got on with implementing this, instead
of cobbling together a set of work-arounds that furnish a perfect analogy to
the inconsitent and frequently proprietarily bloated HTML that browsers
inconsistently supported from one vendor to another throughout HTML's
'growth.'  As long as the sole few ZIG folks continue to find workarounds,
no company is going to build a decent EXPLAIN system besides RMIT -- we'll
all be stuck the the intolerable vapor-ware and shoddy crud made by
Endeavor, for instance.
