     repository := git repository holding project (optional)
     unique_class_name := "0"|"1" (optional, defaults to 0) As a failsafe, forbid naming agents or classes same as the project itself (can cause conflicts in generated header filenames). Disable explicitly (set to 0) only in legacy projects that can not regenerate otherwise, and try to fix those.
     license := optional common tag of the project's license ("MPLv2", "GPL-2.0+", "CompanyName Proprietary" etc.); see also license.xml for longer wording
+    check_license_years := "0"|"1" (optional, defaults to 0) When a project is regenerated, and if any license text(s) are defined, we check that at least one Copyright line in at least one license text contains the current year, and warn if not. If this option is set to "1", we also pause so that interactive developers can see this warning better and intervene.
