+=item versioninstall
+
+If you have C<only.pm> installed on your system, you can use this action
+to install a module into the version specific library trees. This means
+that you can have several versions of the same module installed and
+C<use> a specific one like this:
+
+ use only MyModule => 0.55;
+
+To override the default installation libraries in C<only::config>,
+specify the C<versionlib> parameter when you run the C<Build.PL> script:
+
+ perl Build.PL versionlib=/my/version/place/
+
+To override which version the module is installed as, specify the
+C<versionlib> parameter when you run the C<Build.PL> script:
+
+ perl Build.PL version=0.50
+
+See the C<only.pm> documentation for more information on version
+specific installs.
