Some caveats:
-------------
This software is currently a 
PHP/MySQL software, which means that to
use it you must have a MySQL server 
and a PHP engine (and your web-server
must supports PHP and MySQL). I tested 
the software with PHP 4.3.2 and
MySQL 3.23 (both quite old now), as well as 
PHP 5.0.4 and MySQL 4.1.12.
It may work with even older versions (but it may 
not). Also, the proper 
functioning of this software depend on "proper" 
functioning of you web-server.
In particular, two issues that I came across 
are:
* The scripts must be able to write and create sub-directories in 
the
BASE directory. When using this software on on Linux with an 
Apache
server (running as user "apache"), I had to chdir to the BASE 
directory
and make sure the directory and all the files in it are owned by 
user
"apache".
* The web-server (and the PHP engine) must be willing 
to upload files.
For example, in one system that I used to test it, the PHP 
engine was
configured to only allow uploads of files upto 500KB (and I was 
wrecking
my brains as to why I can only upload pdf and not postscript 
files..) In
my case it turned out that I had to change the parameter 
LimitRequestBody
in php.conf (which on that system was somewhere under 
/etc/httpd/).
