+
+- Added a %rpm_vercmp macro which accepts two versions as parameters and
+  returns -1, 0, 1 if the first version is less than, equal or
+  greater than the second version respectively.
+- Added a %pkg_version macro that accepts a package or capability name
+  as argument and returns the version number of the installed package. If
+  no package provides the argument, it returns the string ~~~
+- Added a %pkg_vcmp macro that accepts 3 parameters. The first parameter
+  is a package name or provided capability name, the second argument is an
+  operator ( < <= = >= > != ) and the third parameter is a version string
+  to compare the installed version of the first argument with.
+- Added a %pkg_version_cmp macro which accepts a package or capability name
+  as first argument and a version number as second argument and returns
+  -1, 0, 1 or ~~~ . The number values have the same meaning as in %rpm_vercmp
+  and the ~~~ string is returned if the package or capability can't be found.
