Klient

Klient offers two ways to add scripts. You can create scripts with Klient's built-in script editor in any language that supports Active Scripting, including VBScript, JScript, Perl, and Python.

Klient adds 70 objects to its script interpretor to extend the script languages and allow script code to talk to Klient.
For the ultimate in speed and flexibility, Klient can also run scripts contained in external DLL files. In addition to functionality, DLL scripts can add custom forms to Klient that appear to be part of the program.
