update-org script

[Harald Weis <hawei@free.fr>]

The "shell script to simplify upgrading to the newest release"
as found on the home page under the Downloads section,
does no longer work as far as I understand.

Most important first: the script should read:

# get the tar file
# [must be a generic name, not a versioned one like org-5.16b.tar.gz]
#wget http://staff.science.uva.nl/~dominik/Tools/org/org.tar.gz
wget http://orgmode.org/org.tar.gz

Obviously, the name of the tar ball must get changed.
 
Then:

# directory where the org directory is located
dir=emacs/lisp
DIR=$HOME/$dir 

# make sure we have the lisp dir
# note that 'mkdir -p $DIR' would not work
# mkdir(1): "The user must have write permission in the parent directory."
mkdir -p $dir

Finally, I suggest a simpler ORGVER line, the argument to ``-f''
is apparently system dependent, in my case it must read ``-f9'':

# what is the new directory name?
# (yes I could use awk, but I can write this line faster than I could 
# check out the man page)
#ORGVER=`tar tvf $TMPTAR | head -1 | sed 's/  */ /g' | cut -d' ' -f6`
ORGVER=`tar tf $TMPTAR | head -1`

It would be nice if the author of the script and
Dominik Carsten could comment.

Thanks in advance.
