+# in simple cases you would use something like
+# %define version 1.0
+# %define taglevel 0
+# that are hard-wired in module-tools by default
+# when this is not your specfile and you want to do minimal changes, you can use redirectors like this
+
+%global module_version_varname fullversion
+# so you can use a pre-existing variable for the version name
+
+# you can use define or global, and redirectors work for taglevel as well of course
+%define module_taglevel_varname mytaglevel

+%global fullversion 1.0
+%define mytaglevel 1
