Vortec is a dedicated Internet Relay Chat client. It has multi-server support, supports sound, has built-in file transfer capabilities, and has a great easy-to-use interface.
Vortec also offers a powerful script engine which allows you to use individual scripts to change the behaviour of, or compliment the main program. Vortec uses Delphi as a base language with many added IRC-specific procedures, functions, and classes. Vortec scripting also incorporates GUI scripting which allows you to create custom windows and controls to interact with your scripts. Scripts can be loaded and saved individually, so you can share your scripts by distributing the script file.
