+llpkgc
+******
+
+This code is generated by the upstream llpkgc repository located at:
+https://gitlab.kitware.com/utils/llpkgc
+
+Generally, updates to llpkgc should be made in the upstream utilities library
+unless they are exceptionally specific to CMake itself.
+
+The upstream repository does not vendor a generated copy of the parser, so
+the associated update script for this dependency runs the generator and
+vendors it appropriately. This requires a reasonably up-to-date version of
+npm be available in addition to the normal 3rd-party update tooling
+requirements.
