Just returned from there, Reinhard (Viet Nam, I mean, not
Sa Pa on this occasion); ADSL ubiquitous :-)  But no-one
in Vietnam is going to try to download the TeX Live DVD from
an Internet cafe in Sa Pa, nor would anyone in their right
mind try to download it with less than broadband, in which
case 587Mb v. 616Mb is a noise-level difference.

And I absolutely disagree with both.  If you use standard utilities,
I accept there is no reason to document them; if you use something
as non-standard as BZ2, then there is every reason to document it.

The instructions tell them not to bother if they don't know how
to proceed.  That's gratuitously offensive and will lead to
others doing what I did : downloading the ISO file at great
cost to everyone because no clue is given as to how to undo
BZ2 compression.

Chr1st, you're now telling me that under the BZ2 there's another level
of indirection ?  This is insane.  ZIP compression does both

But overall, on TeX Live Live, the difference is less than 5%.
noise-level, IMHO.

A world in which ZIP compression is uniquitous and BZ2 niche.
That's the /real/ world, Reinhard, not some ideallistic view
of how it might be.

And they should /not/ be downloading the TeX Live ISO if that is all
they have; the probability of success is (I estimate) less than 1%
over a 56K modem.
