Wow, I must be getting really old. The deja-vu didn't didn't set in
until I slept on it. I can't hardly believe this was 8 years ago.

And at that point ldglite already had experimental support for the
similar gleps code that seems to have disappeared down the memory hole
of the internet.
Unfortunatly I found gleps also produced astronomically large files,
similar to the results reported below. But it's nice to know Travis is
still hammering away at it. I'm confident he'll eventually get the
size to something acceptable, even if we have to wait until googlebyte
local storage is commonplace. :^)
