Thanks, but I did away with that completely.  There's really no need
to think about symblic links and the version file when the version
number actually is embedded in the ACROREAD-PREFIX/bin/acroread
script.  Attached to this mail is the latest version that only runs
acroread -help to determine the patch to the real executable when
the version number was not found directly in $command[$words[1]].

By the way, it uses "sed -n 's/^ver=//p' FILE" to extract the
version.  Is it preferable to use zsh's own string functions to
do this?  The code tends to become quite hard to read, and I usually
need to spend much more time writing it than when I use sed or awk.
