The Visual Linker will be a plugin to the SmartNCode Integrated Development Environment (IDE). It will provide an easy, user friendly visual linking configuration tool.

Visual Linker will ease the linker usage and reduce scripting mistakes thus minimize the time and effort one need to invest in the linking operation.
