Versus is a scripting language originally developed for the IRC client Bisual IRC, and currently used with Visual IRC. It is similar in many ways to the scripting languages used by ircII and mIRC, as well as Tcl and C.
The name "Versus" was chosen because it could be shortened to "VS", which was a common abbreviation for ViRCScript, the language used by Visual IRC '96 through '98. Versus remained mostly backward compatible with ViRCScript, so existing documentation and commentary that mentioned "VS" remained mostly accurate when applied to Versus. The name also alluded to BIRC's origins as a replacement for ViRC.
Object Versus, or OVS, refers to the object-oriented features of Versus. Scripts can define classes and work with objects and methods instead of textual data and aliases; however, in practice, OVS is mostly used to manipulate the VCL objects that make up ViRC's interface.
