What to do next:
Send an email to oca@weizmann.ac.il to request the information on how to download OCA©. Include in the email some information of your site, in the following format: 
$mirror{WIS}   = "http://bip.weizmann.ac.il/oca";
$mirname1{WIS} = "Weizmann Institute of Science, Israel";
$mirname2{WIS} = "";
$mirzone{WIS}  = 3;
$emailnm{WIS}  = "Jaime Prilusky";
$emailct{WIS}  = "oca@weizmann.ac.il";
$acronym{WIS}  = "Weizmann Institute of Science";
$homeURL{WIS}  = "http://www.weizmann.ac.il";

for the mirzone value select one of these
# 1. North and Central America
# 2. Europe
# 3. Africa and Middle East
# 4. Asia
# 5. Australia and Oceania
# 6. South America
LiveUpdate:
OCA© data and software can be updated daily with the 'liveupdate' option. The 'liveupdate' script is part of the new OCA distribution, and can be run manually or as a cron job.
Existing OCA mirrors can download liveupdate here, save it into the /oca-bin directory and set it's mode to executable (chmod +x liveupdate).
To run it, get into the OCA/oca-bin directory and execute it from the command line.
(Perl modules required for liveupdate: Digest::MD5, LWP::Simple)
