Lastly, regarding copying your lib to another acct:

Login to JL's unix acct and type the commands:
telnet 128.135.72.61   (this is the internet id for zaphod)
(login to your old acct on zaphod)
tar cf - lib | compress >amlfiles.tar.Z
(if you're lucky you won't run out of disk space here.  If you do run out
of space, send me mail and I can outline other methods for
copying the files)

(when it's done you'll have a new file on zaphod: amlfiles.tar.Z)
ftp 129.170.16.2       (internet id for u2.dartmouth.edu)
(you'll be prompted for a userid & password.  login to 10514w)
binary            (enter this at the ftp prompt)
put amlfiles.tar.Z
(this will take some time to complete)
quit              (to get out of ftp)
logout            (to logoff zaphod)
******************************************************************
First off, the tar file: the instructions I gave you should have
created a 'compressed' tar file .. this greatly reduces the storage
requirments.  To untar it, you need to do this (the file should have
a .Z suffix .. you didn't mention this in your question ... it's normally
appended by the compress command):
zcat amlfile.tar.Z | tar xf -
The zcat uncompresses it and pipes it to tar.
If you just want to check the integrity of it without untarring it you
can use:
zcat amlfile.tar.Z | tar tvf -
This will list out the contents.
To selectively extract, say lib/ca/colombia.AmWatch and lib/elsalv/q.duarte,
you type:
zcat amlfile.tar.Z | tar xvf - lib/ca/colombia.AmWatch lib/elsalv/q.duarte
