With NSE, software version comparison is performed in system-level, file-level, module-level, and statement-level. In the generated version comparison chart, un-changed modules are shown in blue, deleted modules in brown, added modules in green, and deleted modules in red - to a changed module, we can further view the detailed differences in statement-level.
