    /// NeoLite (https://web.archive.org/web/20000815214147/http://www.neoworx.com/products/neolite/default.asp) was a packer created by NeoWorx.
    /// The most common version appears to be 2.0, with earlier versions existing but with no archived copies available.
    /// NeoWorx was acquired by McAfee in October 2001, who seemingly dropped support for NeoLite (https://web.archive.org/web/20020603224725/http://www.mcafee.com/myapps/neoworx/default.asp).
