You *don't* need this export of CVSROOT -- your previously checked out copy 
of the repository already "knows" where its CVSROOT is.  You *may* need the 
CVSROOT definition when you do the initial checkout, but even then it's more 
convenient to use the "-d" option of cvs, IMHO.  When you do an update, it's 
best to leave cvs to determine the CVSROOT from the definition stored within 
the working copy itself.  Also, if you work on more than one project, having 
an exported CVSROOT could lead to strange behaviour, if you forget to 
redefine it, as you switch between projects.

Your other changes look ok, though.

BTW, why do we recommend -z9 compression?  My understanding is that the best 
overall performance is achieved with -z3 through -z5.  Certainly, -z9 will 
squeeze the data stream more, but at the expense of increased computing time 
for compression and decompression, with an overall loss of performance on all 
but the slowest of dial up connections.

Best regards,
Keith.
