+// of a package are the same. One disadvantage of this approach is that one cannot add an SPDX data file into the

+// the inclusion of an SPDX file. It enables one to quickly verify if one or more of the original package files has
+// changed. The Package Verification field is a unique identifier that is based on SHAing only the original package
+// files (e.g., excluding the SPDX file). This allows one to add an SPDX file to the original package without changing
